Announcements sourced from [this GitHub repository](https://github.com/Rail-Announcements/nexus-tyne-and-wear-metro).

- All the announcements have been rearranged more logically.
- I have removed most duplicate files, but some are intentionally left to maintain the naming convention.
- The file originally named `PHBBN04_N.wav` has been corrected to `PHBN04_N.wav`.
- The file originally named `PNIN14_E.wav` has been corrected to `PHIN14_E.wav`.
- The files `Phsn03_e.wav` and `Phsn03_n.wav` have been corrected to `PHSN03_E.wav` and `PHSN03_N.wav` respectively.
- I have appended `_1` to three filenames of the manual announcements to avoid duplicate names.
