pw_hdlc: Simple, robust, and efficient serial communication

pw_hdlc currently optimizes for robustness and flexibility instead of binary size or performance.

The HDLC encode and decode size report shows the cost of everything needed to use pw_hdlc, including the dependencies on common modules like CRC32 from pw_checksum and variable-length integer handling from pw_varint.

The HDLC encode and decode, ignoring CRC and varint size report shows the cost of pw_hdlc if your application is already linking CRC32 and variable-length integer handling. pw_varint is commonly used since it’s necessary for protocol buffer handling, so it’s often already present.
