* Minor improvements to docs, fix typos, etc.

Fixes
- Fixed calibration bug when a series of constant values confuses statsmodels fb8164aaff9d015d18212b996f68cc47400cb671

Improvements
- Improved performance of `npy2df` 7c6a3b6b9d2e03c89d7aabd059bdb76b4f0790ed
- `lowpass` now doesn't revert the uniform resampling after filtering as it's too costly 953917c46bb724ee7e97f874fd16cde8443d8a89
- Skip resampling if the rate is already satisfied
- Better resampling, now properly supporting non-integer rates 66eb1fe993ecfec45631ff08ee6d535c24649b55
- Many other major works to improve memory consumption of all routines, including using chunking and memmapping.

Other changes
- Deprecate `misc` metrics 88e60d9a959e3bb26944dfd742fb6a614c3ecba9
- Rename temperature column name `T` -> `temperature`
