Support AssertionsOptions in BeEquivalentTo

[souhailelk]

Fixes #58

[dennisdoomen]

🔧 I think it would be very useful to update the example in the readme to illustrate this new capability.
❌ Please ensure the PR description explains what the changes are about, including an example.

@dennisdoomen What do you think of the implementation of IEquivalencyAssertionOptions and the usages?
I'll adjust more the code after your review 😊

[dennisdoomen]

I don't get how you ended up with that implementation. What I was trying to convey in all the comments is something like:

actual.Should().BeEquivalentTo(expected, options => options
    .Using<double>(d => d.Subject.Should().BeApproximately(d.Expectation, 0.1))
    .WhenTypeIs<double>()));

Where options is some kind of interface like IJsonAssertionOptions<T> that (for now) only exposes the Using<T> method in the example. This interface is implemented by a type that inherits from EquivalencyAssertionOptions (from FluentAssertions).

@dennisdoomen, I tried to implement that in my recent commits.
What do you think?
