Remove nrt-specific output dir code

[trey-stafford]

Originally we were only going to produce daily nrt files and they were going to be a part of G02202. Now they'll ne a new version of G10016 and the directory structure for nrt files should reflect this.

Results in dirs that look like this:

/share/apps/G10016_V3/v03r00/dev/trst2284/complete
├── north
│   ├── checksums
│   │   └── daily
│   │       └── 2024
│   └── daily
│       └── 2024
└── south
    ├── checksums
    │   └── daily
    │       └── 2024
    └── daily
        └── 2024

Sure is simpler not to have kwarg is_nrt in so many places!
