Pydeequ to support additional where filters

[andreimekk]

Is your feature request related to a problem? Please describe.
From what I can understand there's no implementation of CheckWithLastConstranitFilterable from Deequ in Pydeequ which makes it impossible to add (.where) method at the end of the defined check. Is there any particular reason for that or it's just part of Deequ that hasn't been implemented yet?

Describe the solution you'd like
Additional class in Pydeequ that extends Check so that we can specify additional SQL WHERE statement to apply before evaluation of the previous constraint.

It's not implemented yet - I think this was planned before #30. I do agree this seems to be a major gap that should be prioritized.

Will do a minor version release around EOW 12/08 - 12/11
