Parse and write .jed files for PAL/GAL/CPLD devices. Compatible with no_std.

Parsing

```rust let parsed = JEDECFile::from_bytes(..., &Quirks::new()).unwrap();

// access bits parsed.f.get(...); ```

Writing

```rust let mut jed = JEDECFile::new(100); jed.header = Cow::Borrowed(b"File written by example tool\n"); jed.f.set(12345, true);

jed.write_io(..., &Quirks::new()).unwrap(); ```
