Polygon

- Marks our **FIRST Production Release**
- the powerful filter options of `lt, lte, gt, gte` (less than, less than or equal to and so on) is patched to work
well. Thanks to Slade Wilson for letting me know about the issue.
- ThinkOrSwim dot notation parser fixed. thanks to fatdragon and Baker XBL for the inputs.
- More control over `timeouts` and limits on `httpx pool`. Came across a limitation while helping in AlbusFrigoris's
use case. Suitable for highly concurrent async applications.

---

- added the new `stock splits` and `stock dividends` endpoints (V3 of both). deprecated the older ones.
- `ticker details vx` is now `ticker details v3` (damn it polygon, stop changing paths). all of the above endpoints are
no longer experimental.
- added support for `dot notation` for option symbols from `tda` (encountered when exporting any data from ThinkOrSwim
or similar tools). thanks to Slade Wilson for the suggestion
- added a function to detect the option symbol format. recognises polygon standard, tda API and ThinkOrSwim dot
notation. thanks to Baker XBL for the suggestion.

---

- added ALL `options endpoints` (newly released)

---

- Update the lib based on changes by polygon to endpoints

---

- Re-did the entire async interface.
- The docs for this version are available [here](https://polygon.readthedocs.io/en/0.8.2/)
- It is highly suggested to upgrade if you're using this version. This was the only version which wasn't backward
compatible

---
All past releases were meant for initial testings and MUST be upgraded to the latest version.
