Add missing Samsung TV IR codes

[lmaertin]

Summary

The current Samsung TV implementation in infrared_protocols/codes/samsung/tv.py is missing several commonly used IR codes that are available in the iwanders/IR_control repository.

Context

I'm currently working on a Home Assistant Core integration (samsung_infrared) that uses this protocol library for infrared control of Samsung TVs. While implementing the integration, I discovered that many useful codes are missing from the current implementation.

Missing Codes (updated):

Power Control (High Priority)

Separate power on command (different from toggle):

POWER_ON = 0x1B # use TV button, because 0x19 not work for me

Color Buttons (High Priority)
These are very common on TV remotes and used for interactive features:

RED = 0x6C
GREEN = 0x14
YELLOW = 0x15
BLUE = 0x16

Media Playback Controls (High Priority)
Essential for media playback functionality:

PLAY = 0x47
PAUSE = 0x4A
STOP = 0x46
FORWARD = 0x48
BACKWARD = 0x45
RECORD = 0x49

Navigation & Menu (Medium Priority)
Additional navigation and menu options:

MENU = 0x1A
GUIDE = 0x1C
TOOLS = 0x4B
MEDIA = 0x31
CONTENTS = 0x5B
SMART_HUB = 0x2E
BROWSER = 0x37
PREVIOUS_CHANNEL = 0x13

Teletext & Accessibility (Low Priority)

TELETEXT = 0x3C
SUBTITLE = 0x25

Picture & Display (Low Priority)

PICTURE_SIZE = 0x3D
PIP = 0x32  # Picture-in-Picture

Additional Features (Low Priority)

E_MANUAL = 0x3F
SLEEP = 0x2F
TV = 0x1B

Source Reference
All codes are documented in: https://github.com/iwanders/IR_control/blob/master/ir_control/codes/samsung_tv.txt

These codes were recorded from a Samsung TV remote (2016 model) and use the Samsung32 protocol with address 0x07.

Impact

• Enables more comprehensive Samsung TV control in Home Assistant
• Provides feature parity with other Samsung IR implementations
• Benefits other projects using this library

Testing

• I have implemented these codes in a temporary class in my Home Assistant integration and verified they work with actual Samsung TV hardware via ESPHome IR transmitter.

If changes are made, can the SAP command be added as well?

Update; Fixed, the ir-sender has been to far away... donno why the other commands worked ;-)

_During my local tests I found that Volume up/down do not work. Since my TV is quite dated (10yrs+), maybe Samsung changed the codes I between.

I'm looking to test your lib stand-alone to figure out wants wrong. I hope we do not need to go for several model variants with different codes._

@abmantis I would like to create PR for the lib as well.

Anything specific to be considered? I'm not aware of any guides for HA lib development.

Nope, just make a PR :)
