Cargo.toml: upgrade to version 0.1.0

Bump version number to release a new crate version.

We're not-so-stable yet, especially with all the changes we had other
the last days, so it seems early to change the major version. On the
other hand, we got many changes since the previous version of the crate:
assembler, disassembler, Rust API to build programs; custom verifiers;
error handling; many fixes, etc. So we'll bump the second digit and tag
version 0.1.0.
