Encode an integer as a 4-byte, little-endian Uint8Array using the number's
two's compliment representation (the format used by JavaScript's bitwise
operators).
Remarks
The C++ bitcoin implementations sometimes represent short vectors using
signed 32-bit integers (e.g. sighashType). This method can be used to test
compatibility with those implementations.
