2111 mag l1d l2 use correct instrument frame for geometry (#2177)

* Replace imap_wkcp.tf with imap_001.tf
Remove IMAP_MAG frame and add IMAP_MAG_BOOM, IMAP_MAG_I, IMAP_MAG_O
Update ID of IMAP_GLOWS frame

* Remove imap_wkcp.tf

* Mark tests broken by removal of IMAP_MAG frame from imap frames kernel with easily searchable xfail

* Add imap_001.tf frame kernel

* Add .tf files to exclude for trailing-whitespace pre-commit
