feat: add support for table column mapping

[dlclark]

This PR adds a feature to map from the model field names to specific database column names.

My use case is that I need to write queries that include table aliases in the where clauses (e.g. select a.id, a.someval, b.id, b.someval from table1 a inner join table2 b on a.id=b.otherid where a.id=?) but I'm unable to represent a.id in the where clause generated by mql today.

To fix this I've added a new mapping option for overriding the model's field name in the where clause. The default behavior is left untouched, but any field name found in the withTableColumnMap (an exact match) will be swapped out for the mapped value when generating the where clause string.

Just a few general items to do:

• Missing change log entry.
• Need to re-generate coverage (make converage) and commit changes

@dlclark -> Ty for the contribution. It looks great. just a few minor bits here and there. Also, the workflows need to be updated which I've opened a PR for against main (#46). Once that's approved and merged, it would be great if you could rebase on that so the workflows can run successfully on your PR. Thanks again.

@jimlambrt ok, in theory I've addressed the comments here, let me know if anything else jumps out.

I'll re-base once the other PR is done.

[dlclark]

@jimlambrt re-base complete.

[jimlambrt]

Ty for the updated commits. I think, we're close. I think you need to run make coverage again and check in the updated coverage.log

[jimlambrt]

Ty again for the contribution.

@dlclark do you need a release, or are you happy to just pull the latest into your project?

[dlclark]

I'm good either way
