Add HT42B534 USB to UART IC

Alex Studer requested to merge github/fork/thatoddmailbox/ht42b534 into master

Datasheet: https://www.holtek.com/documents/10179/11842/HT42B534-xv110.pdf

There are four different packages, and they each have different pinouts, so I made four symbols. The datasheet doesn't give any different part numbers for the packages, so I just added Holtek's names for the packages to end of the symbol names.

All contributions to the kicad library must follow the KiCad library convention

Thanks for creating a pull request to contribute to the KiCad libraries! To speed up integration of your PR, please check the following items:

  • Provide a URL to a datasheet for the symbol(s) you are contributing
  • An example screenshot image is very helpful
  • Ensure that the associated footprints match the official footprint library
    • A new fitting footprint must be submitted if the library does not yet contain one.
  • If there are matching footprint PRs, provide link(s) as appropriate
  • Check the output of the Travis automated check scripts - fix any errors as required
  • Give a reason behind any intentional library convention rule violation.
