l1_rf12.c compiled-in default RF band tables: a round of cleanup * Uncalibrated default g_magic values changed from old Clara RF numbers (yes, Clara, not even Leonardo) to the approximately correct value for our current hw; * Uncalibrated default Rx and Tx channel calibration tables providing neutral correction values: fixed bogus ARFCNs from blind copy-n-paste between different bands; * Restored #if (ORDER2_TX_TEMP_CAL==1) in the Tx temperature compensation tables; * Fully rewrote the big comment before these rf_XXX structures to reflect the current situation. This change is part of the larger transition in FreeCalypso from reverse to forward engineering, from reconstruction of lost original bits to ongoing forward development and maintenance.
