Documentation: Use codelldb by Mason

[theCollectiv]

Feature description

There is a neat* way to set the codelldb path to Mason. Maybe this can improve the documentation:
mrcjkb/rustaceanvim: Supercharge your Rust experience in Neovim! A heavily modified fork of rust-tools.nvim.

-- codelldb: config with Mason
local path = vim.fn.glob(vim.fn.stdpath("data") .. "/mason/packages/codelldb/extension/") or ""
local codelldb_path = path .. "adapter/codelldb"
local liblldb_path = path .. "lldb/lib/liblldb.so"

The advantage is, that codelldb updates do not have to be kept manually in sync or downloaded, if they are handled by Mason.

Thanks! I've updated the existing example in the readme 😄

Actually, come to think of it, mason is so common. I might as well automate that in the default config.

I tried it (new installation of rustaceanvim* + Mason install of rust-analyzer & codelldb) and by opening a rust file, I got that error:

(no further setup or custom config of rustaceanvim done from my side)

Thanks for the update. Will be fixed in #82
