Add end-to-end $binary-vector read/write tests

[sl-at-ibm]

PR #123 introduces $binary serdes format for vectors. The tests (in SerializationTests.cs) use the collection's Check[De]serialization.

• Add a collection read/write roundtrip test with an actual collection. One with a binary in/binary out, one with list in/list out, and mixed patterns.
• Add a collection read/write test with a binary blob (not a vector, just a blob), for the $binary stand-alone format
• What should be tested for vectors on (typed) tables? (class annotations, roundtrip reads/writes)
• Blobs on tables, on the other hand, are all good thanks to existing CreateTable_DataTypesTest_FromObject testing

Create a matrix to cover all test cases (incl. typed/untyped etc)

@toptobes I am taking this one (I was already assignee but just to make sure)
