Avoid leading zeroes in resistance and capacitance values (except 0R)

- boom/lib/e12.inc: several rules produces mal-formed results with leading
  zeroes
- boom/manu/Makefile.common (spotless): added new target to remove
  $(NAME).chr
- boom/manu/Makefile.common (MALFORMED): test for leading zeroes, allowing
  only 0R as an exception
- boom/manu/stackpole/stackpole.gen: catch values < 1 R and convert them
  to mR
