osmo_char2bcd(): Implment hex digits a-f and A-F
osmo_bcd2char() has always supported both decimal and hex. However, osmo_char2bcd() use to only implement decimal digits. With this patch, it also suppots conversion of hex characters from ASCII to BCD. This would be relevant in cases where somebdoy would want to use 'code 11', 'code 12' or 'ST' signals in any addresses (SCCP GT e.g.) Change-Id: I7bbcc6de08024567ab64765c12d7de71df787a7a
