Fix `name`'s extension according to `result_or_mime_type`.
```elixir

{:ok, %Majic.Result{mime_type: "image/webp", ...}}
iex(1)> Majic.Extension.fix("cat.jpeg", result)
"cat.webp"
```
The `append: true` option will append the correct extension to the user-provided one, if there's an extension for the
type:
```
iex(1)> Majic.Extension.fix("cat.jpeg", result, append: true)
"cat.jpeg.webp"
iex(2)> Majic.Extension.fix("Makefile.txt", "text/x-makefile", append: true)
"Makefile"
```
The `subtype_as_extension: true` option will use the subtype part of the MIME type as an extension for the ones that
don't have any:
```elixir
iex(1)> Majic.Extension.fix("Makefile.txt", "text/x-makefile", subtype_as_extension: true)
"Makefile.x-makefile"
iex(1)> Majic.Extension.fix("Makefile.txt", "text/x-makefile", subtype_as_extension: true, append: true)
