release v0.1.0

Added:

• "concise mode" compiler flag -c to make output less verbose and remove warnings
• operator = to make copying/loading single values easier
• raise error on unexpected/invalid token
• warn if ?0 is used because:
• added if statements (without else!) (?0 is reserved for internal purposes)
• added variables

Non-visible changes:

• added "padding" to tokens to reduce risk of out-of-bounds indexing
