* Addition of Go FinishWithFileIdentifier, allows for Go flatbuffer data to contain a file identifier
* adding panic as per review if fileIdentifier does not match length, letting prep pad the file identifier
* updated error message to not use fmt.Sprintf
* using minalign for alignment for file identifier
This is something the format supports, but none of the builders
were doing. Can save 10-20% on FlatBuffer binary size!
Also fixed the Go tests.

Tested: on Linux.
+ Add state to the Builder object to track if we are inside a table,
and if we are finished building the buffer.
+ Use this data to check that a buffer is being built correctly.
+ Panic if a buffer is not being built correctly.
+ Test that the panics happen as expected.
Based on d236dea13d.
Also add a new `insideObject` boolean to the Builder to track whether an
object is currently being constructed. This fixes a bug with objects
that have zero fields.
Builder has a new CreateByteString function that writes a
null-terimnated byte slice to the buffer. This results in zero
allocations for writing strings.
This function gets around the inefficiency of populating a [ubyte] vector
byte by byte. Since ubyte vectors are probably the most commonly used type
of generic byte buffer, this seems like a worthwhile thing to create a
fast path for.
Benchmarks show a 6x improvement in throughput on x64.
There is a new test verifying the functionality of the function.

Implement code generation and runtime library for Go, derived from the
Java implementation. Additionally, the test suite verifies:
- the exact bytes in the Builder buffer during object construction,
- vtable deduplication, and
- table construction, via a fuzzer derived from the C++ implementation.
