+ EVENT_NAME (COUNT = 1)  00:00:01.000  MAJIS  OBS_END    DISK_SCAN

• New datetime formatter for csv export (don't trim millisecondes with zeros):

- 2032-01-01T00:00:01;2032-01-01T00:00:02;MAJIS;S007_01;DISK_SCAN_001;JUPITER;True
- 2032-01-01T00:00:02;2032-01-01T00:00:03;MAJIS;S007_01;DISK_SCAN_002;JUPITER;True

• Changed csv fields order:

1. OBS_NAME (if present)
2. OBS_START and OBS_END
3. OBS_START_REL and OBS_END_REL only if ref/--relative-to is provided
4. Other
5. COMMENTS (in double quotes)

- '#OBS_START,OBS_END,FOO,OBS_NAME,COMMENTS,BAR'
+ '#OBS_NAME,OBS_START,OBS_END,[OBS_START_REL,OBS_END_REL],FOO,BAR,COMMENTS'

• Escape comments value with explicit double quotes (for csv export):

- MULTI WORDS COMMENT with , and ; / MULTI LINES COMMENT
+ "MULTI WORDS COMMENT with , and ; / MULTI LINES COMMENT"

• Change hatch config for linter to require an explicit --fix flag and display --diff in CI.
