Feat/uninitialized var const usage error

[am-cid]

closes #163

---

fn calls

analyzer

• uninitialized vars/consts have underlying type san instead of what they're declared with
• during assignment/declaration, if any errors happen in evaluating the assigned value (if any), they are uninitialized
  • this makes it so they have an underlying type of san
• san values are no longer a valid math operand
  • can only use equality operators

    parser

• combine ArrayDeclaration Parameter and Declaration into just Declaration with a is_param bool to differentiate
  • tbh this is just for easier type checking since these are essentially the same
• Assignment wraps its value with its dtype now
  • dtype is assigned during type checking
• Assignment and Declaration now avoid double wrapping String on string types
• indent while loop properly

lexer

• default initialization of UniqueTokenType
• TokenTypes (the dtypes only) can be converted to python equivalent.
  • this is only used in assignments when wrapping its value
