docs: add france and update orange pl

[fillwithjoy1]

added orange pl to add ims apn. I've just seen too many discussions where wifi calling isn't working unless they added the ims apn.

oh and add compatibility with NRJ mobile carrier (see #175)

close #175

okay just wondering, what happens if a carrier has multiple mnc codes?

@fillwithjoy1 Just adding every available MNC into single cell will be enough.
