buffer: refactor all read/write functions
There are a lot of changes in this commit:
1) Remove the `noAssert` argument from all read and write functions.
2) Improve the performance of all read floating point functions
significantly. This is done by switching to TypedArrays as the
write floating point write functions.
3) No implicit type coercion for offset and byteLength anymore.
4) Adds a lot of tests.
5) Moves the read and write functions to the internal buffer file
to split the files in smaller chunks.
6) Reworked a lot of existing tests.
7) Improve the performane of all all read write functions by using
a faster input validation and by improving function logic.
8) Significantly improved the performance of all read int functions.
This is done by using a implementation without a loop.
9) Improved error handling.
10) Rename test file to use the correct subsystem.
