FIFFT_DIG_STRING_STRUCT type resolver

mne:1.9.0 Recently I face a fif file ，it has the directories of FIFF_DIG_STRING kind in its 107 block, but mne doesn’t provide a parsing method, it causes me to be unable to read scalp points using MNE. I was wondering how to parse this type thanks the fif file [WechatIMG271]

As my colleague raised in another topic, we found that MNE doesn’t parse data of type 234 with the ‘kind’. We decoded it ourselves and plotted the data. The picture shows that these points are exactly the head shape points. I suspect that these data were lost when raw data we’re cropped and re - saved using MNE functions.
