rb: more touch options (#699)

## Link to GitHub Issue or related Pull Request, if one exists
n/a

## Description of change
Add two options:

1. option to adjust poll rate
2. option to change emulation size

Also, the default configuration is changing from:

* ~1000Hz ish to 120Hz (default)
* 3x3 point to 1x1 point

In theory this does not make a meaningful change to how the game plays.
But if people want the old behavior they can change it.

## Testing
Tested on Volzza2 and Reflesia.
