[Feat] Force data types in code

[jredwards]

When I'm running pygwalker from a jupyter notebook, any time I reload the cell that runs pygwalker, I have to go back in and adjust data types (quantitative, ordinal, etc). For data where pygwalker makes assumptions that I don't want, that means fussing with the data tab any time I reload the data. Would be great to be able to specify those in the .walk call or elsewhere.

Hello, thanks for your advice! An argument named fieldSpecs has been provided in #96 and pre-released in pygwalker==0.1.7a3.
Here are some using hints
