per: Slightly optimize encoding of fixed OCTET STRINGs

Do the following optimizations:

* Optimize construction of OCTET STRINGs of size 2 by using
  the 45 opcode instead of the 10 opcode for each character.

* Use exact comparison (implicit by matching) instead of '=='.

* Use list literals when more than one integer is added to a
  list (e.g. [[45,16,2],...] instead of [45,16,2,...]). Results
  in fewer BEAM instructions and less garbage.

* Cons instead of building a nested list when possible. Example:
  [20,TempLen|TmpVal] instead of [20,TempLen,TmpVal].

* Omit the "2" opcode (align to byte boundary) before the "20" and
  "21" opcodes (because they imply alignment).

* Assign the value to be encoded to a temporary variable, to avoid
  calling element/2 more than once.
