Import error with Python 3.13

[jsbrittain]

adtl does not import under Python 3.13 (latest release version). This appears to be due to the new stricter frozen dataclass hierarchies. In particular, the issue seems to relate to pint, and if you import pint you get a very similar error to the one seen below (see https://github.com/hgrecco/pint/issues/ 1969; note that the pint issue was raised in April).

Thanks for raising this @jsbrittain - seems like supporting 3.13 will be blocked until the Pint issue is resolved. I'll mirror what you have done for InsightBoard and add a label to the docs indicating 3.13 is not currently supported.
