Problem

You are given a DataFrame `occupiedbays` with a single column `bay_no`. Each row is the number of a parking bay that is currently occupied. Bays are numbered consecutively across the lot, and `bay_no` is unique.

Find the contiguous blocks of occupied bays. A block is a run of consecutively numbered bays that are all occupied. For each block, report its first and last bay number.

Return `block_start` and `block_end`, ordered by `block_start`.
