-- elixir-tools installs elixir-ls in directories by version and otp version in
-- order to match up the right version with your app.  it doesn't expose what
-- path is in use except for how it launches elixir-ls, so we can scrape it out
-- of there.  it's not clear to me how nvim-dap would handle an adapter's
-- definition changing, so i wouldn't expect this to work well with more than
-- one version in the same nvim session.
