Editing of LC_ENCRYPTION_INFO_64 by Python API

[NewDwarf]

I faced with the problem, LIEF python API doesn't write the changes related to the Mach-O LC_ENCRYPTION_INFO_64 load command.

app = lief.parse("HelloApp")
...
app.encryption_info.crypt_size = 622592    # set new crypt size value
app.write("HelloApp.mod") 

I would expect the changes, specific to LC_ENCRYPTION_INFO_64, are applied into the HelloApp.mod but this not happens.
This was tested on lief 0.16.4-10f74acf with python 3.9.6 on macOS sequoia.
