This commit addresses issue #54 in an attempt to add more bitwise
operators to pocketlang. Tests have also been written to verify that
the operators indeed works as expected.
To add, I also introduced a macro PK_RIGHT_OP that just aliases the
string "Right operand" which was already getting too hardcoded and
appearing too much in the pk_core.c file.
* Fix#54: Add bitwise OR operator and make it available in PKVM
Like the bitwise AND, this is an implementation for pocketlang to
support the bitwise OR operation. In addition, updated "value" ->
"result" in other operation to correctly reflect the container's
purpose. It's indeed the result after the operation, which is a value
too.
In addition, add tests for bitwise AND (&) and bitwise OR (|). Add a
print statement in test file with message that all tests passed with
no errors.
* Fix typo in comment
* Cleanup fixes
