* Fixes#3150
Fixes removeHs removing Hydrides by adding a removeHydrides flag to RemoveHsParameters.
If removeHydrides is false, Hydrogen atoms with formal charge -1 and degree less than or equal to 1 are kept
removeHydrides is kept true by default
* Made suggested changes
Removed extraneous comments and redundant code
Added tests for both ```removeHydrides = true``` and ```removeHydrides = false```
Added tests that ```removeAllHs()``` also removes hydrides
Exposed ```removeHydrides``` parameter to python
* Explicity Added removeHydrides=true in removeAllHs
Corrected typo for removeHydrides
* make formatting consistent

- Add tests for phosphine and arsine chirality
- Add support to isAtomPotentialChiralCenter()
Accept both 2 (implicit H), 3 and 4 coordinate P and As atoms as potential
chiral centers
* get fileparsers catch tests building faster
should use this same approach across all of the catch2 tests
* Fixes#2916
* support parsing of STBOX for atoms and bonds in v3K mol files
add molStereoCare to common_properties
STBOX is translated to the molStereoCare property
* add stereocare support to adjustQueryProperties
make building the catch2 tests faster for the GraphMol package
* copy in AdjustQueryParameters JSON parsing from adapter.cpp
(That still needs to be ported to use the new code)
* get the cartridge using the new parsing code
* update test to reflect new parser behavior
* add a v2000 test
* changes in response to review
