* refactor: replace xtrace with "print_and_execute" function
* nit: stylize error messages
* replace out_expected.txt with measurements_1B.out
* print
* prevent errors on cleanup
* run tests and check warmup run output before running benchmark
* move "git diff" pretty diff output to test.sh
* Ensure "set -e" is re-enabled if we followed a "continue" branch
* add timeouts to test.sh invocations
* use diff with tocsv.sh to show differences on failed test
* add --quiet mode to test.sh
* move prepare_$fork.sh invocation to right below hyperfine since test.sh also invokes it
* Revert "add --quiet mode to test.sh"
This reverts commit 13e9fb7f395c1bd64a62528b8349803bc1366941.
* use tee to capture test output to a temp file and print contents on failure

The script tests all implementations and prints PASS or FAIL status.
In case of failure it also prints implementation output to stderr.
This will be handy for adding new test samples.
Show test statuses and omit failing output:
```sh
$ ./test_all.sh 2>/dev/null
PASS artsiomkorzun
PASS baseline
PASS bjhara
PASS criccomini
FAIL ddimtirov
FAIL ebarlas
PASS filiphr
FAIL itaske
PASS khmarbaise
FAIL kuduwa-keshavram
FAIL lawrey
PASS padreati
FAIL palmr
PASS richardstartin
FAIL royvanrijn
FAIL seijikun
PASS spullara
PASS truelive
```
Show only passing implementations:
```
$ ./test_all.sh 2>/dev/null | grep PASS | cut -d' ' -f2
artsiomkorzun
baseline
bjhara
criccomini
filiphr
khmarbaise
padreati
richardstartin
spullara
truelive
```
For #61
