Refactored nodes, added categories, Implemented FloatPrimitive

[ScrewTSW]

• Refactored nodes
• Set subcategories for each node type
• Implemented new FloatPrimitive - the default PrimitiveNode had very broken behavior when it comes to value piping and precision

CAUTION:

• .nodes.ToString.RF_ToString has major issues - unusable
  The node can be piped to and from
  Upon execution the node fails with following error:

Failed to validate prompt for output 57:
* RF_ToString 91:
  - Return type mismatch between linked nodes: value, FLOAT != INT,BOOL,FLOAT,NUMBER

I tried multiple format inputs based on ComfyUI Code, still get parsing errors:
type array of strings:

Failed to validate prompt for output 9:
* RF_ToString 91:
  - Return type mismatch between linked nodes: value, FLOAT != ['BOOL', 'INT', 'FLOAT', 'NUMBER']

type string "*"
