TLVService mixin

A service class that provides functionality for encoding and decoding Type-Length-Value (TLV) data format.

The TLV format is a flexible encoding structure used in many communication protocols and data formats. Each data unit consists of a:

• Tag: A 2-character identifier representing the type of data.
• Length: A 2-character field that specifies the length of the value.
• Value: The actual data associated with the tag, whose length is defined by the length field.

Example:

• For a TLV string like 0012345A:
  • Tag: 00
  • Length: 12 (indicating the value field is 12 characters long)
  • Value: 345A
