Support specifying the number of lines scrolled by the mouse

Is your feature request related to a problem? Please describe. No, it would be a feature to specify the lines that will be skipped when using the mouse scroll

Considering that if we open a huge text file, scrolling using the mouse scroll that currently only skips one line at a time is tiring

Describe the solution you’d like I thought of it more or less like this:

var tv = new TextView()
{
    // ...
    VerticalLinesToScroll = 5, // Anyway, any number, the default is 1, as it is currently
    HorizontalLinesToScroll = 3 // Anyway, any number, the default is 1, as it is currently, but in this case, the number would be to use with the command Shift + Mouse Scroll, which comes by default to scroll horizontally in the TextView
};

Extra note: If the values ​​are not specified, the values ​​will be the same as those that come by default in a TextView

Extra Note 2: Hope I’m not bothering you with so many issues

This is great stuff. Please don’t stop helping make this library better!

I think it would also be awesome if the values could be made dynamic and be easily changeable after the widget is created.

This way, developers can implement use cases for additional scenarios such as being able to hold down modifier (or other) keys to scroll at different paces. (I.e. hold down CTRL to scroll 100 lines, SHIFT to scroll 10, etc.)
