Subject: [PATCH] Add a requirement on iconv and suggest mbstring in
 `composer.json`

The iconv PHP extension is used in `ParserState` and hence needs to be
required.

The mbstring extension is optional, but helpful. So we should help
users discover this with a `suggest` entry in the `composer.json`.
