Support for mambajs's environment lockfile format

[Klaim]

Description

NOT FINISHED YET

Add support for mambajs environment lockfile format in addition to the currently supported conda/mamba environment lockfile format.

Both formats don't provide the exact same set of information so we try to at least provide and use what's mandatory and fill in the additional data depending on the format.

The code implementing the parsing of each format has been put in separate cpp files, but the public api is unchanged, so one could just call the public api with either kind of file and we dont need to change anything on the cli front.
