Patch neovim 0.7.0 compatibility

Version 0.8.0 added indexed vim commands, like vim.cmd.hi, additionally, until this release groupnames could not consist of @ or . characters.

Tested on versions 0.7.2 and 0.10.3

note: on 0.7.2 errors are no longer thrown, however, the current page shows the wrong colours until it is scrolled, which is quite peculiar!

see here:

• default nvim colorscheme
• after applying colorscheme
• after page scroll.

Additional information for the ending note

the colouring issue seems to only occur if it is changed after the file has been loaded, as such, setting the colourscheme in your init.lua avoids the problem all together. 👍

Thank you for the PR, but I think you'd need to make these changes in the fennel code, otherwise it might end up being lost when another change gets made. I'll see if I can maybe do it

Okay, I'll look into it when I have some time, thanks for the note!
