update pyarrow requirement to ^14.0.0?

[emileten]

pyarrow below 14.0.0 is incompatible with python 3.12. Since lonboard specifies pyarrow versions with ^13.0.0 (14.0.0 excluded), installing lonboard with python 3.12 leads to failures.

Should we change the pyarrow requirements to pyarrow=^14.0.0 to allow for python 3.12, or explicitly indicate that python 3.12 is not supported?

We needed to bump to 14.0.1 anyways because of a security disclosure: GHSA-5wvp-7f3h-6wmm. Fixed in #230
