[pixiv] respect more query parameters for user URLs

The API endpoint responsible for user illustrations does not
provide sufficient filter capabilities* to match the actual
website, so we are spinning our own filters.

Respected parameters are
    'type': illust, manga, ugoira
    'tag' : any image tag (this was already supported)
    'p'   : the page to start on

*
- API can filter for illustrations and manga, but not for ugoira.
- 'offset' is applied before filtering
- no 'tag' filter
