add some patterns for lazy loading

[max397574]

just some things (I just write those here because I think they don't exist yet and are quite nice)
you can consider which (if any) are worth implementing

groups for keys wbthomason/packer.nvim#1063

patterns for commands like NvimTree* or NvimTree{Toggle,Open,Close}

ig for autocommands this should work anyway (haven't looked at the code yet though)

I'm planning to make some improvements to the keys handlers.

Patterns for commands is not something I'm interested in. Thank you for the suggestions
