* #Rust Create a crate for reflection
* #Rust Add a crate for reflection tests and helper to access schema
* #Rust Get root table of a buffer and access field with schema
* #Rust Add 'Struct' struct and corresponding getter
* #Rust Add functions of getting any table/struct field value as integer/float/string
* #Rust Add setters for scalar fields
* #Rust Add setter for string fields
* #Rust Add getter for Table/Vector fields
* #Rust Add buffer verification
* Add a 'SafeBuffer' struct which provides safe methods for reflection
It verifies buffer against schema during construction and provides all the unsafe getters in lib.rs in a safe way

* Update release script to update Rust version (it still needs to be published after)
* Also update rust while I'm at it

* [Rust] Add length checks to arrays and vectors.
The previous behavior allowed for out of bounds access in
the public API (#7011).
* bump semver and test warning

* fix for rust build
* Rust: Implement Serialize on generated types
For debugging convenience it is really handy to be able to dump out
types as another format (ie: json). For example, if we are logging a
type to a structured logging system, or even printing it out in a
structured way to the console.
Right now we handle this by shelling out to `flatc` which is not ideal;
by implementing Serialize on the generated types we can use any of the
Serializer-implementing packages for our structured debug output.
* clang-format
* Make the flatbuffers Rust crate only have an optional dependency on the `serde` packages.
* fix warning
* fix rust test build
* Oh yeah this needs to be initialized
* fix toml syntax
* code review feedback
* rebuild test data
* benchmark many vtables
* Rust: Store written_table rev-positions sorted.
The previous implementation was slow if there were too many tables.
Asymototically when inserting the n^th vtable: The old implementation
took O(n) lookup steps and O(1) insertion. The new implementation is
O(log n) lookup and O(n) insertion. This might be improved further by
using a balanced btree.
Benchmarking, create_many_tables is 7.5x faster (on my laptop):
// Simple vector cache
test create_many_tables ... bench: 728,875 ns/iter (+/- 12,279) = 44 MB/s
// Sorted vector cache
test create_many_tables ... bench: 97,843 ns/iter (+/- 4,430) = 334 MB/s

Also, rename `new_with_capacity` to `with_capacity` to match
how `Vec` does it.

* Fix Miri flag passing and bump Rust version.
* Fix Miri problems from Arrays PR.
SafeSliceAccess was removed for Arrays. It's kind of unsound.
It has two properties:
1. EndianSafe
2. Alignment 1
We only need 1. in create_vector_direct to memcpy data.
We both 1. and 2. for accessing things with slices as buffers are built on &[u8]
which is unaligned. Conditional compilation implements
SafeSliceAccess for >1byte scalars (like f32) on LittleEndian machines
which is wrong since they don't satisfy 2.
This UB is still accessible for Vectors (though not exercised our
tests) as it implements SafeSliceAccess. I'll fix this later by
splitting SafeSliceAccess into its 2 properties.
