Add the Moon gravity grid dataset

[leouieda]

Description of the desired feature:

We now have a Moon gravity grid at 10 arc minutes: https://github.com/fatiando-data/moon-gravity-10arcmin

Including it here will be very similar to the way the Earth grid function is implemented.

Are you willing to help implement and maintain this feature?

Yes but welcome anyone to do it.

Hello, I cloned the project and as usual, I always run the test before starting to edit the code. In this case, when the test is already failing due to redundancy, what do you recommend? I couldn't find any redundancy in the init.py file. Is there any related issue regarding this? Additionally, I noticed that in the project repository verde, in the same folder where _version.py exists, there is also another file named _version_generated, which I didn't notice in the ensaio project. Do you know anything about this? I had the same error in the boule project when I ran the tests.

Hi @Phssilva could we move this discussion to the forum https://github.com/orgs/fatiando/discussions ? It has nothing to do with this particular issue. Could you start a post in the forum, please?
