Ry

- internal
- cleaned up several dependencies and features
- `ryo3-zstd`
- actually changed to use py buffer protocol this time... I dont know how it
got missed before...
- re-factored a decent bit and made submodule with future plans to expand encoding/decoding dictionary
support
- submodule is `ry.zstd` and/or `ry.ryo3.zstd`

---

- `ryo3-reqwest`
- client configuration for pickling
- allow buffer-protocol for `body` fetching methods (should add string maybe?)
- `ryo3-walkdir`
- Few more options added
- `ryo3-glob`
- new wrapper around `glob` crate
- `ryo3-jiff`
- Switched to use conversions from `jiff` feature of `pyo3-v24` as opposed to
hand-rolled conversions we had before

---

- pyo3 version `0.24.0`
- `ryo3-which` functions return `pathlib.Path` now due to changes in pyo3-v24;
this may change in the near future...

---

- dependencies updated
- pickling support and tests for several types
- bytes/buffer-protocol support for several sub-packages/packages:
- `ryo3-brotli`
- `ryo3-bzip2`
- `ryo3-flate2`
- `ryo3-fnv`
- `ryo3-xxhash`
- `ryo3-zstd`

---

- internal
- types split up and cleaned up
- `ryo3-size`
- `ry.Size` object
- `ryo3-jiff`
- `series` iterators have `take` function that takes a `usize` returns a list
of size `usize`
- updated series types to be `JiffSeries` class

---

- `ryo3-std`
- `fs`:
- `read_stream` function that returns an iterator of `ry.Bytes` objects from
a `PathLike` object
- Several more fs functions added
- `ryo3-tokio`
- Several more tokio fs functions added
- internal
- reorganized type annotations to be not a HUGE file...
