[Bugfix] Attempted fix of Offset issues and utilizing enums

[F9Alejandro]

Changes to chameleon_cmd.py:

Created SlotNumber Enum with two staticmethods:

• list: List all choices that can be made based on the name of the enum instead of value
• fix: Takes the value and checks against an enum name that has been manipulated and converted to an int, if they match it outputs the value of the name/value enum pair

Added two staticmethods to TagSenseType Enum:

• list: Same as what SlotNumber does above it lists all possible choices in a pretty print (not used for actual choice)
• choices: Used for the actual choices and is only the value itself

All instances of slot_num/index have been set to the type enum of SlotNumber

• Usage of SlotNumber.fix is used to convert from "name" to value of the enum pair

  All instances of sensetag have been set to the type enum of TagSenseType

• No further changes where made as it is still using value (no trickery here)

Changes to chameleon_unit.py:

• Made changes to SlotIndexRequireUint to properly reflect changes made in cmd.py
• Made changes to SenseTypeRequireUint to properly reflect changes made in cmd.py

Further testing may need to be done.

Changes to be committed:

• modified: software/script/chameleon_cli_unit.py
• modified: software/script/chameleon_cmd.py
