Implemented Typeof + conversion system

[UwUDev]

Added:

• Typeof rule
• .typeof() that convert any JavaScript value to their type name
• PosNeg rule (basically -... and +...)
• .as_js_num() that convert any JavaScript value to a Raw(Num(n)) or Nan
• Substract (basically ... - ...)

Updated:

• NotBool to handle any JavaScript values
• Many utils functions to work with the new .as_js_num()
• CombineArrays to handle more additions

Fixed:

• .as_bool() for Bytes()

Removed:

• NegInt rule (now handled by PosNeg)
• StringPlusMinus rule (now handled by PosNeg)
• BoolPlusMinus rule (now handled by PosNeg)
• substract from CombineArrays (now hadled by Substract)
• substract from AddBool (now hadled by Substract)
