Made Location::try_new public (#7775)

In order to get observational islamic date for locations other than
`MECCA` and `CAIRO`

Example:

```rust
let new_york = Location::try_new(40.7, -74.0, 10.0, -5.0 / 24.0).unwrap();
let fixed = fixed_from_gregorian(2026, 3, 13);
let (year, month, day) = observational_islamic_from_fixed(fixed, new_york);
println!("Observational NYC: {day}/{month}/{year}");
```

## Changelog

calendrical_calculations: Changed `Location::try_new` from `pub(crate)`
to `pub`
 - New Methods: `Location::try_new()`
 - New errors: `LocationOutOfBoundsError`
