Remove FieldElement::from_square

Browse Source 
The new `FieldElement::from_u256` is sufficient to load an unreduced value. The
caller can perform the square themselves, without us explicitly supporting this
special case.

Updates the monero-oxide version used to one which no longer uses
`FieldElement::from_square` (as their use is why it was added).
