perf: strip binary and optimize for size

This change adds stripping and optimization for size. As most operations
in tm are waiting on IO and scanning file directories there is not a big
difference between optimizing for performance compared to size.

 There were two different changes tested.

 - strip: Strip and perf opt
 - small: Strip and size opt

hyperfine -w 10 "./tm-curr" "./tm-strip" "./tm-small"
Benchmark 1: ./tm-curr
  Time (mean ± σ):      44.7 ms ±   1.6 ms    [User: 56.8 ms, System: 159.5 ms]
  Range (min … max):    42.2 ms …  49.8 ms    47 runs

Benchmark 2: ./tm-strip
  Time (mean ± σ):      44.0 ms ±   1.0 ms    [User: 57.1 ms, System: 160.9 ms]
  Range (min … max):    41.3 ms …  46.4 ms    52 runs

Benchmark 3: ./tm-small
  Time (mean ± σ):      45.5 ms ±   1.1 ms    [User: 64.0 ms, System: 159.6 ms]
  Range (min … max):    43.3 ms …  48.4 ms    51 runs

Summary
  './tm-strip' ran
    1.02 ± 0.04 times faster than './tm-curr'
    1.04 ± 0.04 times faster than './tm-small'

 From this I found that there was no real difference between the two but
 there was a difference in binary size.

dua tm-*
   1.92 MB tm-small
   2.64 MB tm-strip
   3.57 MB tm-curr

The reduction in size is significant and was chosen over perf.
