Add IMAP_HRC frame to SpiceFrame enum and update science frames kernel to v1.2.0

[Copilot]

• Create imap_science_120.tf in tests/spice/test_data/ (copy of imap_science_100.tf with IMAP_HRC frame at ID -43930 added)
• Remove old imap_science_100.tf from tests/spice/test_data/
• Copy imap_science_120.tf to ultra/l1c/sim_spice_kernels/
• Update spice/geometry.py to add IMAP_HRC = -43930 to the SpiceFrame enum
• Replace all references to imap_science_100.tf with imap_science_120.tf in all Python files
• Verify test coverage - existing test_spice_frame_enum iterates over all SpiceFrame members and now covers IMAP_HRC
• All affected tests pass

<issue_title>SPICE - Add IMAP_HRC frame to SpiceFrame</issue_title>
<issue_description>### Algorithm Description:

Nick has added the frame to the imap science frames kernel. This ticket is for adding that frame to the SpiceFrame enum.

1. Add the new imap_science_120.tf to the repo in the tests/spice/test_data directory, replacing imap_science_100.tf
2. Replace all references to imap_science_100.tf with the new imap_science_120.tf
3. Add the new IMAP_HRC frame defined in the new imap science frame kernel to the SpiceFrame enum in spice/geometry.py
4. Check test coverage of the SpiceFrame. There may be tests that iterate over SpiceFrame members that provide needed test coverage. If not, add test coverage exercising some geometry calculation using the new IMAP_HRC frame.

@copilot, please remove the old science frames kernel: imap_science_100.tf from the spice test_data directory.

@copilot, please remove the old science frames kernel: imap_science_100.tf from the spice test_data directory.

Done — removed imap_science_100.tf and added imap_science_120.tf to tests/spice/test_data/ in commits b068493 and 5a17e8c. (The file required force-adding since test_data/ is in .gitignore.)
