* Fixed handwire helper table and image size
* Fixed a heading
The subcommand functions' name follows the Python convention of using
snake case, but looks odd on the command line.
Fix it by converting underscores to dashes, eg.: list_keyboards ->
list-keyboards.
While this was historically a valid possibility, nowadays, it reads
kinda weird, and the [Oxford Dictionaries Online suggests to avoid it](https://english.stackexchange.com/a/56010).
Thus, I removed it everywhere I found it.
* Add a short explanation to the troubleshooting section
While translating I noticed that the troubleshooting section could use a
little bit more explanation. @Yanfali was so kind to chime in on this on
discord and explained that this was ment for people who accidently
forget to put their board in bootloader mode, so I added this as a
possible common mistake.
Also fixed the spelling of Msys2 to MSYS2 and Halfkay to HalfKay as
these are the official spellings they use themselves.

`list_keyboards` replicates the `make list-keyboards` by globbing for all paths
that include `rules.mk` and then removing the paths that include `keymaps`.
This basis of this cli command could be reused in the future as a util, but is
not done so here since this would be the only place that would use it currently

I2C timing parameters were seemingly set up for an STM32F303 target MCU, at a specific clock speed. This commit allows specifying the timing parameters via config.h, allowing other STM32 MCUs to be targeted, potentially at different clock frequencies.
Alternate function modes for the I2C pins are now also configurable, allowing for remapping to other pins.

With my XD60, I noticed that when typing the backlight was flickering.
The XD60 doesn't have the backlight wired to a hardware PWM pin.
I assumed it was a timing issue in the matrix scan that made the PWM
lit the LED a bit too longer. I verified it because the more keys that
were pressed, the more lighting I observed.
This patch makes the software PWM be called during CPU interruptions.
It works almost like the hardware PWM, except instead of using
the CPU waveform generation, the CPU will fire interruption
when the LEDs need be turned on or off.
Using the same timer system as for hardware PWM, when the counter
will reach OCRxx (the current backlight level), an Output Compare
match interrupt will be fired and we'll turn the LEDs off.
When the counter reaches its maximum value, an overflow interrupt
will be triggered in which we turn the LEDs on.
This way we replicate the hardware backlight PWM duty cycle.
This gives a better time stability of the PWM computation than pure
software PWM, leading to a flicker free backlight.
Since this is reusing the hardware PWM code, software PWM also supports
backlight breathing.
Note that if timer1 is used for audio, backlight will use timer3, and if
timer3 is used for audio backlight will use timer1.
If both timers are used for audio, then this feature is disabled and we
revert to the matrix scan based PWM computation.
