Addr import/export
Read a Word from addr in base-256 representation.
@n is the number of bytes to read.
The endianness is selected with the Bool# parameter: write most significant
byte first (big-endian) if 1# or least significant byte first
(little-endian) if 0#.

@n is the number of bytes to read.
Read a Word from addr in base-256 big-endian representation.
@n is the number of bytes to read.
Write a Word to addr in base-256 representation and
return the number of bytes written.
The endianness is selected with the Bool# parameter: write most significant
