Fix build issues due to maturin & py03 versions

[orieg]

This PR bump maturin and py03 versions to latests. It also update the Makefile to properly run make test on MacOS.

This should fix #33

Note that to successfully build on a MacOS M1, you may need the following rustflags defined in ~/.cargo/config

[target.aarch64-apple-darwin]
rustflags = [
  "-C", "link-arg=-undefined",
  "-C", "link-arg=dynamic_lookup",
]

Output from make test:

$> make test
cp target/debug/libtantivy.dylib tantivy/tantivy.so

thanks, this did the trick for me, also fwiw, afaics a rustup install doesn't need the cargo config, but a brew install rust does.

[update] never mind I did need the cargo config to get things working.

[update 2] the set of workarounds for building without the cargo config changes is documented here https://pyo3.rs/master/building_and_distribution.html#macos
