Added regex parameter for set_type

[roll]

@akariv Here is an issue with field names interpreted as regex - https://github.com/BCODMO/frictionless-usecases/issues/9

What do you think of adding a parameter regex/use_regex/disable_regex/exact_value/? (not sure about naming) set to true by default or something like this to add an ability to disabling as regex interpretation?

It's WIP if it makes sense I'll add tests/docs and a dpp update.

It works for me using e.g. this example:

  - run: set_types
    parameters:
        resources: data
        regex: false
        types:
          temperature (24h):
              type: integer

Yes, this great proposal and implementation, thanks @roll!
