Adding TPA6110A2

Adding the TPA6110A2 stereo headphone amplifier to the Amplifier_Audio library. It was largely copied from the existing LM4810. I'll be writing a merge request for the new HVSSOP-8 footprint in the footprint library as well. The checker script did not report errors.

Required Settings:

Please configure your personal fork of the KiCad project with the following settings:

1. Settings->General->Visibility->Pipelines should be enabled and set to "Everyone with access".
2. Settings->CI/CD->General Pipelines timeout should be set to >3h .

Configure the merge request as follows:

1. The "Allow commits from members who can merge to the target branch." option check box at the bottom of your merge request must be checked.

• This can later be enabled via the edit button found at the top right (in case you forgot to do it when creating the merge request).

#General Guidelines: 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 automated check scripts - fix any errors as required
• Give a reason behind any intentional library convention rule violation.
