Fix ISO 14443-B tag simulation

[michi-jung]

See https://github.com/RfidResearchGroup/proxmark3/issues/1652

• Fix Bit Coding PICC -> PCD: Encoding for 0 and 1 bits were reversed.
• Add a frontend delay for TR0 (No subcarrier) in TransmitFor14443b_AsTag.
• Remove unconditionally prefixing the encoded data with two '1' bits.
• Improve the Type B PICC State Machine implementation.

With these improvements my PCD can read the ISO 14443-B tag emulated by a Proxmark3 Easy.
