Windows bindgen feature

[simonrw]

While debugging issue 118 I suggested the use of the bindgen feature. This builds the bindings from scratch using bindgen on that platform, however there are issues with building under windows that seem to not be due to bindgen but from fitsio-sys-bindgen.

can I ask have you tried adding the bindgen feature to your Cargo.toml?

It starts to download & build a bunch of crates, but eventually fails with:
