Used for writing the decoder test macros. This is already a dependency in the parquet crate, so bringing it into parquet-variant.

If it is only used in tests, perhaps we can move it to dev-dependencies

Created macros and grouped similar tests together in order to reduce some of the boilerplate test code.

According to the spec, all the decimal variants have a max scale of 38.

- I think this somewhat overlaps with @scovich 's PR here: [Variant] Add negative tests for reading invalid primitive variant values #7779
#7779 does not include any decoder tests though
I think we could potentially avoid checking the scale/precision for decimals in the decoder and let the higher level validation check them

That makes sense. I removed the extra scale validation.

Thank you @superserious-dev -- I think this is a very nice improvement. I have some suggestions on how to improve the testing, but I don't think they are required
I suspect there will be some conflicts to resolve after I merge #7776 which I am about to do
