**Full Changelog**: https://github.com/freqtrade/technical/compare/1.4.2...1.4.3

Add compatibility alias for zema (will raise a warning when called for the first time).

Mostly a maintenance release, increasing compatibility with uptodate dependencies.

* Remove zema, as it's implementation was actually a dema

New indicators:
* `tv_wma`, `tv_hma`, `chopiness`.
* disable `qtpylib.vwap()` as that's implicitly forward-looking. Use `qtpylib.rolling_vwap()` instead.
* fix some bugs in qtpylib, causing certain cases to fail.
* update master-branch to main branch.
* Remove some unused dependencies (arrow), which will improve compatibility with more systems
