Supersedes #190
Pre-calculate all profiles/plumes, but additionally also compress them using simplify-js. This has a massive effect on the size of the profiles (reducing from 5000 points to 10-ish while still looking roughly the same (within 1% but a bit less fluent).
To also work with skew-T diagrams this code assures p, T and Td share the same vertical coordinate, all other variables are compressed independently.
This fixes #183 leading to more performant plots, especially when using the time slider
Touches upon #186, but doesn't fix it yet. However, global extent calculation now becomes much easier.
