nvim-treesitter depencency check to prevent errors

As the modules depend on nvim-treesitter. I think it could be nice to add a little dependency check if it is installed.

It could be as simple as a: if not pcall(require, "nvim-treesitter") then return end inside lua/module-template.lua.

If preferred, it could include a little print to inform the end user of the module about the missing dependency: print "module-template requires nvim-treesitter to be installed"

Would a PR on this have a chance?

And of course, I'll be back at my desk on Sunday to submit the PR 👍
