✨ make use of IQueryable on Select method

[Odonno]

Thank you for submitting this pull request! We appreciate you spending the time to work on these changes.

What is the motivation?

Fixes #61

What does this change do?

Creates a Query Builder that supports the built-in IQueryable<T> interface of .NET.

• Trade IEnumerable<T> for IQueryable<T> for Select method
• Convert IQueryable into a query string when lazily called (or parameterized query string when parameters are detected)
• Support most common Linq methods (Select, SelectMany, Where, OrderBy, Take, Skip, GroupBy, Min/Max/Sum/Average/Count, Distinct, Contains, First/Last/Single, Any/All)
• Add Async methods, following the EF async extensions to improve performance (no sync locking)
• Add a variety of tests (to avoid possible regression in the future)

What is your testing strategy?

Unit & integration tests
