Protoplasm

Changed

- Moved this entire project over to Github
- Bumped the version in order to not confuse older stuff that doesn't expect
protoplasm to exist in Pypi.org (if we end up migriting this there and
just open-sourcing the whole thing)
- Also in case something changes in the API while migrating, cause I tend
to fiddle with the code and tidy up and refactor when moving stuff

Added

- Docker image building of the latest stable version of Protoplasm and all
its dependencies to this project for both Alpine and Debian and Python
versions 3.8-3.12
- Thus, checking in and publishing a new stable version of Protoplasm
should trigger new Docker base images with Protoplasm and all the gRPC
binaries up-to-date and ready to be used by other projects (speeding up
their testing and building considerably)
- ...at least in the old CI/CD environment... We'll see what's what once
this is all in Github and Github Actions

Changed

- A ton of CI/CD stuff that's irrelevant now that we've moved to Github

Fixed ANOTHER bug in type hint importing

Fixed

- Now importing `List` and `Dict` with nested dots work (e.g. `List[foo.Bar]`)

Fixed bug in type hint importing

Fixed

- Now importing `List` and `Dict` works (was only `typing.List` and `typing.Dict` before)

Added

- Added the `ResponseIterator` which remote method calls with stream output now return as a wrapper around the previously returned iterable results.
- Added `TimeoutResponseIterator` which wraps the new `ResponseIterator` with timeout functionality while waiting for response stream iterations.
- `ResponseIterator` has a `with_timeout()` method which automatically wraps it in a `TimeoutResponseIterator`
- Both `ResponseIterator` and `TimeoutResponseIterator` have a `one_and_done()` method which waits for one next response stream iteration and then closes the stream.
- `RequestIterator` can now take in a `list` or `tuple` as `initial_request` to load up multiple initial requests.
- Added `close()` method to `RequestIterator` to close the request stream (force a cancel event)
- Added `unpack()` to `DataclassBase`

Major update that unifies the API and functionality of versions 2 and 3.

Skipping a bunch of versions and checkins between 3.0 and 4.0 cause they're
not really important at the moment (it's 2024 and I'm migrating this from
our internal Gitlab repo to Github).

Added

- Unify the unary functionality of Protoplasm 2 with the streaming
functionality of Protoplasm 3
- The two turn out to be completely incompatible and API shattering
Protoplasm 4 must incorporate BOTH functionalities wile being backwards
compatible enough for both Protoplasm 2 and 3 projects to be able to
migrate to 4
-The key here is detecting the `stream` keyword in protos that denote
streaming input and/or output
- Add piled up functionality/utility/QoL improvements/bugs that's been on The
List™ for a while
- Cast to/from base64 encoded strings
- Utilize the `__all__` directive to isolate `import *` side effects
- Integrate the Neobuf Builder CLI (from various other projects) into
Protoplasm and generalize it
- Address the "`None` is default value" issue
- Explore the pros/cons of making non-existing Message/Object attributes
return `Empty` or `EmptyDict` to simplify nested attribute fetching...?

Changed

- Refactor and restructure the package properly
- Separate the 4 main roles of the package logically
1. Cross-piling `*.proto` to `*_pb2.py` and `*_pb2_grpc.py`
2. Cross-piling `*_pb2.py` to `*_dc.py` Neobuf Dataclasses
3. Generating `*_api.py` interfaces
4. Generating gRPC implementation of Services
