Updated NIM FOV definitions by adding the NIM neutral/ion mode and the thermal mode FOVs as indicated by Andre Galli. In order to facilitate a more one-to-one correspondance with SPICE Archives, following the advice from NAIF and in order to improve and make the meta-kernel management easier: earlier versions of files which have or have not been included in a meta-kernel will NOT be moved to the former_versions directory in the FTP as they used to. Instead all files will be kept in the directory and file management will be done solely via the meta-kernel. This change is applied retroactively. This does not apply to the meta-kernel directory.
