Moved inst module to lib
...
As it has no dependencies on vm specifically, and it's more necessary
for any vendors who wish to target the virtual machine, it makes more
sense for inst to be a lib module rather than a vm module.

Implemented new types of EQ, forced all comparators to push bytes
...
Just need to call their unsigned versions.
All comparators should push bytes as it makes return types uniform.

vm_execute_all: Print every cycle on VERBOSE >= 2, just print final state otherwise
...
Changed VERBOSE checks to ensure a degree of information.

Created routines for new comparator opcodes (not implemented)
...
Will cause error if used currently, which is fine.

Introduced new instructions for comparison
...
Comparing signed and unsigned versions of numbers. Same for EQ as
well.
Notice the irregular pattern of BYTE, CHAR, INT, HWORD,LONG,WORD as
OPCODE_IS_TYPE requires the subcodes to be surrounded by BYTE and
WORD.

Added a "usage" message and colours for assembler
...
Prints useful and pretty messages when verbose being at least 1.

Fixed bug where reading operand bytecode may stop prematurely
...
This is due to checking for equality instead of just greater than in
darr->used against darr->available.

Fixed bug where printing hword of an instruction prints number not hex
...
This is an easy fix.

Moved base functions from inst.c to dedicated file
...
Doesn't make sense for them to be in the VM module when they have a
more general purpose now.

vm/main takes a filename as input to execute bytecode
...
Also prints a usage for incorrect usage.

Make root directory an include path, set #include's properly
...
Easier to write includes now just using < with the module name, in
comparison to using relative paths.

src->vm, Makefile is now a bit more abstracted and pretty colours
...
Changed folder names for sake of clarity (will be introducing a new
build target soon), and Makefile can now easily support more targets.
