Subject: [PATCH] enhance(filetype): filetype option as fallback of file
 extension for icon detection (#415)

* enhance(filetype): filetype option precede extension for icon detection

Enhances icon detection for files without extension e.g. shebang or
modeline by using filetype option before the extension.

* fixup(filetype): filetype option as fallback of file extension

Some file icon keys defined by [nvim-web-devicons][1] using file
extension name instead of filetype option.

There's been an [issue][2] about this but no PR for it yet, so I think
for now we can handle it here.

* refactor(filetype): `vim.api.nvim_buf_get_option` -> `vim.bo`
