sane.ds: Support SANE Backends that treat resolution as TYPE_FIXED.

Most SANE backends store resolution in DPI as an integer value TYPE_INT.
Some store it as TYPE_FIXED. Twain always uses TW_FIX32 for resolution.
Provide access in ICAP_xRESOLUTION and DG_IMAGE/DAT_IMAGEINFO/MSG_GET
for both types.

Cache resolutions before SANE_Start as some backends do not
allow option read access after scanning started any more.
