More Code Review Updates * Add more testing for ReadOnlySpan parsing * Update `AssertReadFromParseContext` to also run assertions for a `ParseContext` initialized from a `ReadOnlySpan` of the given input. * Remove passing `ReadOnlySpan` parameters by ref since they are not altered and the type isn't large enough to benefit from performance improvements for passing by `ref` or `in` * Update `ParseContext` `Initialize` overloads for `ReadOnlySpan<byte>`, going down to two (since nothing was calling the overload that changed the recursion limit). The first now calls the second to set the `buffer` and `state` on the context, and has documentation to note that it is used to create a `ParserInternalState` with default settings.

Protocol Buffers (a.k.a., protobuf) are Google's language-neutral, platform-neutral, extensible mechanism for serializing structured data. You can find protobuf's documentation on the Google Developers site.
This README file contains protobuf installation instructions. To install protobuf, you need to install the protocol compiler (used to compile .proto files) and the protobuf runtime for your chosen programming language.
The protocol compiler is written in C++. If you are using C++, please follow the C++ Installation Instructions to install protoc along with the C++ runtime.
For non-C++ users, the simplest way to install the protocol compiler is to download a pre-built binary from our release page:
https://github.com/protocolbuffers/protobuf/releases
In the downloads section of each release, you can find pre-built binaries in zip packages: protoc-$VERSION-$PLATFORM.zip. It contains the protoc binary as well as a set of standard .proto files distributed along with protobuf.
If you are looking for an old version that is not available in the release page, check out the maven repo here:
https://repo1.maven.org/maven2/com/google/protobuf/protoc/
These pre-built binaries are only provided for released versions. If you want to use the github master version at HEAD, or you need to modify protobuf code, or you are using C++, it's recommended to build your own protoc binary from source.
If you would like to build protoc binary from source, see the C++ Installation Instructions.
Protobuf supports several different programming languages. For each programming language, you can find instructions in the corresponding source directory about how to install protobuf runtime for that specific language:
