Rust implementation of EIP-55

When passing a string without a prefix, the checksum()
function fails.
The function accepts both prefixed and non-prefixed strings. However, indexing for characters is performed without taking this into account. This results in a panic during execution.
This library depends on unmaintained and vulnerable rust-crypto. This probably doesn't introduce any security issue, but it would be nice to replace it with something modern like sha3 crate from RustCryptoOrg.

Steps to reproduce
eip55::validate_address("Îñţérñåţîöñåļîžåţîờñ");
Panics with:
byte index 1 is not a char boundary; it is inside 'Î' (bytes 0..2) of `Îñţérñåţîöñåļîžåţîờñ`
thread 'project::test::check_invalid_addresses' panicked at 'byte index 1 is not a char boundary; it is inside 'Î' (bytes 0..2) of `Îñţérñåţîöñåļîžåţîờñ`'
I'm using the latest version:
eip55 = "0.3"
Please consider the following snippet I've tried it on replit:
// correct checksum
const ADDRESS: &str = "0x000000000000000000000000000000000000dEaD";
fn main() {
// NOTE: This is incorrect, valid form is `..dEaD` as above
assert_eq!(
checksum("0x000000000000000000000000000000000000dEAD"),
"0x000000000000000000000000000000000000dEAD");
// and hence wrong result here
assert_eq!(
validate_address("0x000000000000000000000000000000000000dEAD"),
true);
