Add bail out

[fmartinsons]

Hello,

this MR principally add the Bail Out! pattern support as defined in https://testanything.org/tap-version-13-specification.html.
I also add an option to make the xml output compact and improve XML generation for tests that have been not found (for example after a Bail Out).

I also added a test file to emphasize the change. For information this test file gives

<?xml version="1.0" encoding="utf-8"?>
<testsuites disabled="0" errors="0" failures="2" tests="5" time="0.0">
	<testsuite disabled="0" errors="0" failures="2" name="test-bailout" skipped="0" tests="5" time="0" hostname="SGX-CMP-776">
		<testcase name="/MyTest/1"/>
		<testcase name="/MyTest/2"/>
		<testcase name="/MyTest/3"/>
		<testcase name="None">
			<failure type="failure" message=" (0)"/>
		</testcase>
		<testcase name="None">
			<failure type="failure" message=" (0)"/>
		</testcase>
	</testsuite>
</testsuites>

for the master and

<?xml version="1.0" encoding="utf-8"?>
<testsuites disabled="0" errors="1" failures="1" tests="5" time="0.0">
	<testsuite disabled="0" errors="1" failures="1" name="test/fixtures/test-bailout" skipped="0" tests="5" time="0" hostname="SGX-CMP-776">
		<testcase name="/MyTest/1"/>
		<testcase name="/MyTest/2"/>
		<testcase name="/MyTest/3"/>
		<testcase name="Bail out for Test 4">
			<failure type="failure" message=" (0)"/>
			<system-err>Fatal condition met which prevent to continue</system-err>
		</testcase>
		<testcase name="Test 5 missing">
			<error type="-1" message="missing (-1)"/>
		</testcase>
	</testsuite>
</testsuites>

We will need to reestablish tests on GitHub Actions.

[fmartinsons]

Ok, can I do something for that ?

Closing and reopening to rebase.
