[NODES] Implement automatic conversion between certain data types

[itsmattkc]

Some conversions can be handled automatically (with some degree of manual override):

Examples (not exhaustive):

• Float -> Vec (with options on whether to set the X, Y, etc. or all)
• Vec -> Float (with options on which element to use as the float or to average)
• Audio -> Float

Would love to see that feature implemented !
