feat(cellRange,dataValidation): add support for cell range <dataValidation type="list"> and absolute coordinates

[flhorizon]

Closes https://github.com/qrilka/xlsx/issues/156

• add cell range support
• add absolute coordinate support

Basically when I needed to implement flavours of mkRange mkSingleCellRef and matching from* functions, I've kept historical behaviour and types and instead wrote "prime" variants mkRange' etc

Hi @flhorizon Thanks for contributions, I'm back from my vacation so should have some time to review them. In this case - would you mind splitting warnings-related changes from "real" code? It doesn't help to review them both in the same PR. Thanks

Hi @qrilka ! Thank you for your time. I've removed the commit about warnings for both my PRs. Are you interested in it for another PR? It mostly affects /test

[qrilka]

Sure, why not, even small improvement counts

Please also take care of the name clash with microlens

Hi @qrilka !

I've done the 2 last changes you asked for and moved CellRef test definitions to a separate module

Thanks
