Stock-indicators

New features:

- .NET 7 (preview) target - 773
- HL2, OC2, HLC3, OHL3, OHLC4 selection `CandlePart` options for SMA, EMA, and WMA - 772

Not-really breaking changes, to rename a few things:

- `ConvertToQuotes()` renamed to `ToQuotes()`, to be consistent with the C `ToList()` style.
- `GetDoubleEma()` renamed to `GetDema()`
- `GetTripleEma()` renamed to `GetTema()`

I've set the old names as Obsolete, so you'll get a compiler Warning to help you find where and how to rename things. The old names still work, so they're not technically broken.
