Implement `alpha` and `epsilon` for chemistry `BlockEncoding`s #1247

Open charlesyuan314 opened 3 months ago

These methods from the BlockEncoding interface need to be implemented for {Single,Double}Factorization{OneBody,BlockEncoding} for these parameters to be automatically propagated to composite block encodings.

Is it well understood what epsilon should be for these methods which have multiple epsilon contributions.
