Add method for recovery of Edwards x-coordinate given Montgomery (u, v). 
This function is necessary for matching Signal's hash_to_point() behaviour.

Fixup CompressedMontgomeryU::decompress() and ensure no divide-by-zeroes. 
Also, match Signal behaviour, and split off recovery of other
coordinates into separate functions.
