Release 0.7.0

[Woyten]

It would be great if the latest state was released to crates.io. In particular, it fixes the following incompatibility problem with cpal which I need in version 0.12.x for WASM support:

package `alsa-sys v0.1.2`
    ... which is depended on by `alsa v0.2.2`
    ... which is depended on by `midir v0.6.2`
    ... which is depended on by `microwave v0.9.0 (/home/user/workspace/rust/tune/microwave)`
links to native library `alsa`

package `alsa-sys v0.3.0`
    ... which is depended on by `alsa v0.4.2`
    ... which is depended on by `cpal v0.12.1`
    ... which is depended on by `microwave v0.9.0 (/home/user/workspace/rust/tune/microwave)`
also links to native library `alsa`
