Pflotran output

[MoiseRousseau]

Description

Add two new export formats: PFLOTRAN (export_pflotran_input) and FLAC3D (export_flac3D_input).
Also add a function which create the vertices coordinates and the block defined by their vertices id.

Relates to #557

Note the PFLOTRAN output may need the h5py library to enable hdf5 output format. I did not change the dependencies and installed h5py on my own.

Hi @MoiseRousseau sorry for the very late response. Thank you for your contribution!

Can you add a small test (probably in gempy/test/test_addons/test_export) also can help to know how to use the function

Hi @Leguark !
Sorry also for the late response. I am currently in the last month of my PhD so I did not have so much time right now.
I would have a look to the small test you ask soon. Also, to help know how to use the function, I could write a piece a documentation as it is done for the MOOSE exportation capability under the "integration" folder (https://docs.gempy.org/integrations/gempy_export_MOOSE.html).
Have a nice day!

Hi @Leguark,
I finally update the exportation function and provided an example in the integrations folder. Now, exporting a PFLOTRAN mesh is automatically documented in the integrations section.
Please let me know what you think and if it can be merged.
Have a nice day,
Moise

Looks good so far, we'll maybe have to write one, two small tests for the export functions.
