Errors in tests

@fxpineau - If I try to run the tests I get these errors:

error: Could not compile `cdshealpix`.

To learn more, run the command again with --verbose.

This is on macOS with rust installed via Homebrew. This is what I have:

(gammapy-dev) hfm-1804a:cds-healpix-rust deil$ rustc --version
rustc 1.27.0
(gammapy-dev) hfm-1804a:cds-healpix-rust deil$ cargo --version
cargo 1.26.0

Can you reproduce? Do I need a newer version of rust?

[fxpineau]

You have to update with rustup update

[cdeil]

Looks like I have to uninstall rust from Homebrew first to be able to isntall rustup.

I'll do that, but could you please clarify min version needed in the README?

Now I get this error:

[fxpineau]

You can try:

cargo update cargo clean cargo test

Or install the nightly version (but you are supposed to need it only for bench)

rustup install nightly cargo test +nightly

[fxpineau]

I removed the need for the nightly compiler.
