2023-10-31	Remove duplicated code	Aryadev Chavali

2023-10-31	Implemented all the comparators	Aryadev Chavali
	So much reused code, I definitely need to find a way to make this cleaner.
2023-10-31	Use standardised signed version of word type from base.h	Aryadev Chavali

2023-10-31	Moved inst module to lib	Aryadev Chavali
	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.
2023-10-31	Implemented new types of EQ, forced all comparators to push bytes	Aryadev Chavali
	Just need to call their unsigned versions. All comparators should push bytes as it makes return types uniform.
2023-10-31	vm_execute_all: Print every cycle on VERBOSE >= 2, just print final state ↵	Aryadev Chavali
	otherwise Changed VERBOSE checks to ensure a degree of information.
2023-10-31	Created routines for new comparator opcodes (not implemented)	Aryadev Chavali
	Will cause error if used currently, which is fine.
2023-10-31	Introduced new instructions for comparison	Aryadev Chavali
	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.
2023-10-29	Added a "usage" message and colours for assembler	Aryadev Chavali
	Prints useful and pretty messages when verbose being at least 1.
2023-10-29	Fixed bug where JUMP_REGISTER couldn't be in bytecode read	Aryadev Chavali

2023-10-29	Fixed bug where reading operand bytecode may stop prematurely	Aryadev Chavali
	This is due to checking for equality instead of just greater than in darr->used against darr->available.
2023-10-26	Fixed bug where printing hword of an instruction prints number not hex	Aryadev Chavali
	This is an easy fix.
2023-10-26	Moved base functions from inst.c to dedicated file	Aryadev Chavali
	Doesn't make sense for them to be in the VM module when they have a more general purpose now.
2023-10-26	vm/main takes a filename as input to execute bytecode	Aryadev Chavali
	Also prints a usage for incorrect usage.
2023-10-23	Make root directory an include path, set #include's properly	Aryadev Chavali
	Easier to write includes now just using < with the module name, in comparison to using relative paths.
2023-10-23	Added lib folder for general stuff, introduced as target to Makefile	Aryadev Chavali

2023-10-23	Implemented simple example of a for loop in main	Aryadev Chavali

2023-10-23	src->vm, Makefile is now a bit more abstracted and pretty colours	Aryadev Chavali
	Changed folder names for sake of clarity (will be introducing a new build target soon), and Makefile can now easily support more targets.
