GSmartControl: allar útgáfur og eldri útgáfur

- Support GCC 11 (and Ubuntu 22.04) by using and vendoring fmt library (#77).
- Support an option of saving smartctl output to text instead of JSON (#76).
- Restored pre-2.0.0 runtime support for smartctl < 7.3 (based on Text parser); this is an unsupported, old method without NVMe, provided for compatibility only (#77).
- Restored pre-2.0.0 support for standard (non-extended) self-test log found in very old ATA drives; the new JSON parser did not support this previously (#79).
- Better support for temperature values in JSON parser; this fixes unreasonably large temperature values (#78).
- Add a tooltip explaining self-test "lifetime hours" wrapping behavior (#73).
- Windows: Fixed a crash on Windows 7 when opening drive information by using Windows 7-compatible librsvg (#71).
- Windows: Avoid using non-integer font sizes.
