Extension of code for STM32F1 to allow for dual bank series XL. Small changes to documentation for F2, F4 and L1 to add a parameter reference. Tested with STM32F103RBT6 (note: tests show that the PG bit must be cleared after programming, otherwise a subsequent erase attempt fails. This has been added to flash_program_half_word for F0 and F1 only. A fix for the other families is not included in this PR.)
