Replace conditions collection with dictionary

[luispfgarces]

Description

For performance reasons, this PR replaces the references:

• IEnumerable<Condition<TCondition>> by IDictionary<TCondition, object>
• IEnumerable<Condition<string>> by IDictionary<string, object>

[!WARNING] BREAKING CHANGE: conditions are no longer accepted via a collection of Condition and a dictionary is accepted instead. As such, all calls to MatchOneAsync(...), MatchAllAsync(...), and SearchAsync(...) will need adjustment to provide a dictionary of conditions alternatively.
