fix timer capture TI1/TI2 bug
Somewhat confusingly, the TI1/TI2 fields for capture/compare channels 2
and 4 are both flipped compared to channels 1 and 3 and do not
correspond to the binary numbers.
Section 15.4.7 of RM0008 (STM32F1 series) and Section 12.4.7 of RM0368
(STM32F4 series) read:
CC1S: Capture/Compare 1 selection
01: CC1 channel is configured as input, IC1 is mapped on TI1
10: CC1 channel is configured as input, IC1 is mapped on TI2
CC2S: Capture/Compare 2 selection
01: CC2 channel is configured as input, IC2 is mapped on TI2
10: CC2 channel is configured as input, IC2 is mapped on TI1
This commit closes github issue #12 reported by GatorCh.
