When generating components, to reduce the number of components, they are
merged as follows:
- For every MCU, the "ref without flash" is calculated by replacing the
11th character in the ref name with an `x` and cutting off everything
after the package character.
- MCUs that share the same pinout will be merged if their ref names without
flash are the same
- The name of the component will be generated as follows: STM32F429IEHx +
STM32F429IGHx + STM32F429IIHx = STM32F429I[EGI]Hx.
- To achieve a stable UUID even if new MCUs are added, the "ref without
flash" is combined with the SHA1 hash of the pins.
Because renaming the pinout might result in a different UUID, when
upgrading the stm-pinout database, changes (but not additions) must be
analyzed manually.
