Fix inconsistencies in rank-local SVD wrapper

[wavefunction91]

Addresses #262

This PR implements the following changes:

1. The rank-local SVD wrapper now does the "right" thing viz reallocating U/VT to the right dimensions based on the desired outputs.
2. Changes the default behaviour to be "SomeVec" as opposed to "AllVec" to coincide with ScaLAPACK APIs
3. Adds flexibility in the rank-local SVD wrapper to allow for all allowable "Job" types for XGESVD in LAPACK
