aes: bump version to v0.7.0-pre; update README.md table

Bumps the `aes` crate version to indicate we'll be making breaking
changes before the next release (i.e. `cipher` crate upgrade).

Also removes the `aesni` and `aes-soft` crates from the README.md table
now that they've been unified into the `aes` crate (#200)
