Fixed a deeply unpleasant UI hang. Sorry!

I fixed a long-standing bug with notification scheduling and timezones

### 1.1.0 — 2024-02-25

I've had a lot of fun optimising the performance of this app via algorithm analysis, massive parallelism, and cleverer pre-processing. The result? Now the processing stage while we calculate your notifications takes about 5 seconds - before, it could take over a minute.
