Type-Length-Value8 (TLV8) for python

Type-Length-Value (TLV) are used to encode arbitrary data. In this case the type and length are represented by 1 byte each. Hence the name TLV8.

A TLV8 entry consists of the following parts: * the type: this 8 bit field denotes the type of information that is represented by the data. * the length: this 8 bit field denotes the length of the data (this does not include the 2 bytes for type and length. For data longer than 255 bytes, there is a defined procedure available. * the value: these length bytes represent the value of this TLV. The different types of data is represented differently: * bytes: this is raw binary data and will be used as is, no further interpretation takes place * tlv8: this is a specialized case of bytes values. Using this instead of pure bytes enables nesting of data and creating a hierarchy. * integer: integers are stored in little-endian byte order and are encoded with the minimal number of bytes possible (1, 2, 4 or 8) * float: floats are stored as little-endian ieee754 numbers * string: strings are always UTF-8 encoded and do not contain the terminating NULL byte
