using names from TCL_Roku_TV.ir even though the power signal matches TCL_ROKU_US.ir
if you were trying to make an ultra-generic version of just the roku remote then just make note that these two extra media provider buttons have these codes:
```
#
name: Sling
type: parsed
protocol: NECext
address: EA C7 00 00
command: 06 F9 00 00
#
name: Now
type: parsed
protocol: NECext
address: EA C7 00 00
command: 6C 93 00 00
```
Files are now organized into subdirectories based on manufacturer/brand.
Where possible, files have been updated to a naming standard:
Example: "Brand_Model.ir"
These changes should allow for faster finding of necessary files, and
the naming standard should keep things fairly cohesive across the board.
This is a proposed change and I'm absolutely open to feedback to
make it better before merging- thanks!
