FunctionClauseError: Meilisearch.Error.cast/1

[cwc]

We have occasionally encountered the following error in our application:

FunctionClauseError: no function clause matching in Meilisearch.Error.cast/1
  File "lib/meilisearch/error.ex", line 135, in Meilisearch.Error.cast/1
  File "lib/meilisearch/client.ex", line 58, in Meilisearch.Client.handle_response/1
  File "lib/meilisearch/search.ex", line 148, in Meilisearch.Search.search/3
  <snip>

It appears that for some reason, the body of the request to Meili is neither nil nor a map. I believe it is likely an error message - a binary - but there is no function clause for cast/1 in error.ex to handle this and return it to our application.

I believe this could be fixed by adding a clause to handle a binary body, by returning a Meilisearch.Error where the body is in the message key of the Error struct. I can open a PR to make this change if you like the idea.

Sorry for the delay, I don't use actively this lib any more.
If you still need these changes, feel free to make a PR, I will merge ASAP.
