@jreback i think you wrote most of this, do you remember what the reso checks here are for?

needs a rebase, this overalaps with #31096 ? |
rebased+green. the diff overlaps so 31096 will probably need to be rebased, but they are logically independent. |

Most of _get_string_slice is duplicated inside PeriodIndex.get_value, which likely explains why get_string_slice has almost no test coverage. This also brings PeriodIndex.get_value into closer alignment with DatetimeIndex.get_value, so we may be able to share code a few steps from here.
