Add option to hide the end of buffer icon (~)

[nguyenanhhao221]

Is your feature request related to a problem? Please describe.

I would like to have an option in the config to hide the end of buffer icons easier.
Currently, this could be done by override the highlight EndOfBuffer to have the fg the same color as the background.

Describe the solution you'd like

This is my proposed solution..

    opts = {
      show_end_of_buffer = true,
}

We can have an additional option like above to achieve this easier
