Crash on C-ScrollWheel* mapping

[andis-sprinkis]

After adding this code to my init.vim

let s:fontname = "CascadiaCodePL"
let s:fontsize = 10

function! AdjustFontSize(amount)
  let s:fontsize = s:fontsize+a:amount
  let s:guifont = s:fontname . ':h' . s:fontsize
  execute 'set guifont=' . s:guifont
endfunction

call AdjustFontSize(0)

noremap <C-ScrollWheelUp> :call AdjustFontSize(1)<CR>
noremap <C-ScrollWheelDown> :call AdjustFontSize(-1)<CR>
inoremap <C-ScrollWheelUp> <Esc>:call AdjustFontSize(1)<CR>a
inoremap <C-ScrollWheelDown> <Esc>:call AdjustFontSize(-1)<CR>a

and doing C-ScrollWheel* in a new neoray instance, it would exit with this error:

Manually calling :set guifont=CascadiaCodePL:h{some number} works fine.

This now fixed in latest release. Also you can use the font size increase/decrease keybinding with mouse input. Just set them like this.

let neoray_key_increase_fontsize=<C-ScrollWheelUp>

0.0.8 - these mappings work without crashing now, thank you :)
