Do not always specify uv-file when it is the same as ssh-file.

`MAX_RADIUS_deg` is not general enough for a non longitude latitude
grid. The variable `max_radius` moves from module `input_ssh_m` to
module `config_m`. The variable `MAX_RADIUS_deg` disappears. The
constraint `2 * max_radius_deg(1) < 180` becomes `4 * max_radius(1) <
nlon` but is only applied to the periodic case because we do not have
the general equivalent of 180° in number of points.

`Region_1_20454_cyclone_3/config_nml.txt` is a symlink to
`Extraction_eddies_region_1_noise/config_nml.txt`.

Call `input_ssh` from main program `test_mean_speed`. This is
necessary because procedure `mean_speed` uses variable corner from
module `input_ssh_m`. Note that we have to call config before
`input_ssh` since `input_ssh` uses a variable from module `config_m`.

In program `test_set_max_speed`, read `cont_list_proj` instead of
computing it. Computing it is not possible with a non
longitude-latitude grid.

Read the same NetCDF files than those used to create `cont_list`. It
does not change anything since the window is going to be created
inside `test_set_max_speed`, so it is an unnecessary complication to
have input NetCDF files on a restricted domain. Furthermore, if we
want to use `test_set_max_speed` on a non longitude-latitude grid,
then it would be a problem to convert x, y corresponding to the grid
of `cont_list` to x, y corresponding to a restricted grid.

For `Test_compare` version > 0.4.

Rather than from current series of tests.

This variable was already used in other tests.

Because some tests require results from other tests in this series of
tests.

Because it can be created by analysis scripts.

It must be the same than the one used for other input files of the test.

Remove input file `outside_points_get_1_outerm.csv`. Use result from
test `Region_1_20454_cyclone_3` instead. There is one less point in
the file `outside_points.csv` from the test `Region_1_20454_cyclone_3`
but this does not change the results of the two impacted tests:
`Get_1_outerm` and `Extr_proj`.

The only difference in the test specification of
`Get_1_outerm_noise_2` with test `Get_1_outerm` is the input file
`outside_points.csv`. This difference in specification leads to no
difference in results of the two tests. The input file
`outside_points.csv` for `Get_1_outerm` is problematic because it has
an extra point at (9.375, -35.857) which corresponds to a cyclone for
an old version of SSH data. So we are going to change the input file
of `Get_1_outerm` to take
`$tests_old_dir/Region_1_20454_cyclone_3/outside_points.csv`, the same
one than for `Get_1_outerm_noise_2`, so there is really no use for
`Get_1_outerm_noise_2`.

Remove input file `outside_points_get_1_outerm_noise_2.csv`. Use
result from test instead.

Motivation: provide file `outside_points.csv` instead of keeping it in
`Inst_eddies/Tests/Input/Region_1`.

To new version provided by Aviso.

There is no significant difference with
`Extraction_eddies_region_1_noise`: no impact of `min_amp` on this
region. For an impact of `min_amp`, compare tests
`Extraction_eddies_region_3` and `Extraction_eddies_region_3_min`.

Read path to the pre-existing `cont_list` shapefile on the command line.

We rewrite `inst_eddies_Aviso.py` so it is more convenient to use. The
script is only useful for several input files. Otherwise we can
directly use `inst_eddies.py`. So instead of optional arguments
template and last date, we use positional arguments. Then there is no
point in distinguishing dirname and basename. Also, it does not make
sense any longer to read the date from the content of the first
file. The script becomes more general: we do not assume that all input
NetCDF files are in the same -directory and that the time coordinate
is in days since 1950-1-1. The interface is also clearer.

`config_nml` should be the same for `test_get_1_outerm` and
`test_set_max_speed`.

Remove unused procedures and programs `inside_4`,
`max_speed_contour_ssh`, `test_inside_4`,
`test_max_speed_contour_ssh`. Unused since commit 99e2e1b1.

Since we now have the test `SHPC_degenerate`.

To replace `Inst_eddies/Tests/Input/SHPC_degenerate`. The motivation
is to have the `cont_list` shapefile, so we can use it with
`test_set_max_speed`.
