Add panasonic ac climate component

[WeekendWarrior1]

What does this implement/fix?

I have been using esphome to control my Panasonic AC (via IR) for over a year with a custom component, thought it was finally time to get an official component going. Tested and working on my AC.
Currently doesn't do any of the Panasonic presets "eg. eco, quiet, powerful", they seem to really mangle the IR packet.

Awesome!!
Finally something I actually have in my house I can test =)
I just quickly built a receiver and transmitter and tested this and it worked first time.

Excellent, I am glad to hear. I will fix the failed lint and add to the docs in the coming days.

The ON/OFF byte is different for my unit though, could be because it should only look at/set a single bit in message[5] Mine works with 0x0A/0x0B instead of 0x08/0x09.
I also have added horizontal/vertical/both swing support locally so far as mine supports that.

What model is your AC, and what does your remote look like?
The ones in my home are the CS-MRE7QKR, and my remote is:

I also have added horizontal/vertical/both swing support locally so far as mine supports that.

Can you please elaborate on what you mean by this?
Did setting

    supports_horizontal_swing: true

In the climate config not make those swing modes visible in HA? (I believe it should)

[jesserockz]

No, setting that did not work. But also I modified it to not use a define and allow setting of each mode from yaml. I can push this commit if you are interested?

Indoor unit: CS-E18NKR

Please do!

Hey there @glmnet, mind taking a look at this pull request as its been labeled with an integration (climate_ir) you are listed as a codeowner for? Thanks!

Can we rename this platform to be panasonic_ir as there is an external component that uses the serial port that should eventually make its way into ESPHome. https://github.com/DomiStyle/esphome-panasonic-ac/tree/dev-cztacg1
