What's Changed

* Don't fillna whole dataframe as part of indicator calculation
* simplify usage for `vwmacd` and `td_sequential` (they return the original dataframe with new columns now).


**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
*

Convert the project to use `pyproject.toml`.
Use the black formatter to format code (so the code-style is somewhat aligned throughout the repository)

Improve resample / merge logic to use data as soon as it'll become available (as soon as the long candle closes).
