Issue #20: Add a --shout flag that upper-cases the greeting

Add `pub shout: bool` to `Options` in `src/lib.rs`, set by `--shout` in `parse_args`. In `src/main.rs`, when set, print the greeting upper-cased (`HELLO, ADA!`). Add unit tests in `src/lib.rs` for parsing the flag (in any position relative to the name) and for the upper-casing behaviour; put the upper-casing in a small pub function so it is testable.

These commands must pass when you are done. Run them if the tools are installed:
- cargo test
- cargo run -- --shout Ada

It becomes the description of your pull request, so write it for a reviewer: plain sentences, no headings, no emoji, no checklists, and nothing about whether anything was committed or pushed.

  11. I added a `--shout` flag that upper-cases the greeting. `cargo test` passes (15 tests), and `cargo run -- --shout Ada` prints `HELLO, ADA!`. `Options` in `src/lib.rs` now has `pub shout: bool`. `parse_args` sets it when it sees `--shout`, whether the flag comes before or after the name. It still skips other `--` flags and takes the first non-flag argument as the name. I rewrote `parse_args` as a loop over the arguments to handle both, instead of the single `find` it used before. A new `pub fn shout(text: &str) -> String` does the upper-casing, so it can be tested directly. `src/main.rs` calls it on the greeting when the flag is set. The new unit tests cover: - `shout` defaulting to false. - `--shout` before the name, after the name, and with no name. - The upper-casing itself. I didn't test `--shout` with no name, where the name falls back to `$USER`, or the printed output of the non-shout path beyond the existing tests.
