Merge rust-bitcoin/rust-bitcoin#750: Use test_data for big objects, add big block for benchmarking

247a14f Use test big block for bench_stream_reader instead of making one (Riccardo Casatta)
b92dfbb exclude test_data when publishing the crate (Riccardo Casatta)
f5a9681 include a big block in test_data, use it for ser/de benchmark (Riccardo Casatta)
09dada5 Move bip158 test vectors to test_data (Riccardo Casatta)
06d1a82 Remove testnet block hex from tests, use test_data with include_bytes! (Riccardo Casatta)

Pull request description:

  In the first two commits I moved some data from source files to the newly introduced `test_data` dir, including it with `include_[str|bytes]!` macro.

  The second-to-last commit introduces a big block in test_data which is very handy in ser/de benchmark (I used it for #672) because with smaller blocks you may not notice performance improvements.

  Since I don't want to pollute the package the last commit excludes the `test_data` dir from the published package. I think it's fine to do it because dependent packages don't run dependencies tests.
