Upgrade NuProcess library.

Created by: brettwooldridge

NuProcess v1.1.3 contains changes for Linux that massively reduce the amount of garbage generated during stream handling of spawned processes.

Before (< v.1.1.3):

Iteration   4: 14.460 ops/s
                 ·gc.alloc.rate:      6.760 MB/sec
                 ·gc.alloc.rate.norm: 693246.857 B/op
                 ·gc.count:           ≈ 0 counts
                 ·threads.alive:      11.000 threads
                 ·threads.daemon:     10.000 threads
                 ·threads.started:    11.000 threads

After (v1.1.3+):

Iteration   4: 21.312 ops/s
                 ·gc.alloc.rate:      0.656 MB/sec
                 ·gc.alloc.rate.norm: 52814.261 B/op
                 ·gc.count:           ≈ 0 counts
                 ·threads.alive:      11.000 threads
                 ·threads.daemon:     10.000 threads
                 ·threads.started:    11.000 threads
