added metatadata + data for MSA dissection SD/LD

assays/MSA_dissection/protocols/dissection_of_MSAs.txt

+- per genotype: choose approx. 4 random plants every 6-8 days (SD) or every 2-10 days (LD)
+- start 5 days after emergence (DAE)
+
+- remove the leaves surrounding the main shoot apex (MSA) with a blade
+- image MSA with the stereo microscope Nikon SMZ18 with a Nikon DS-Fi2 camera
+- score developmental stage according to Waddington et al. (1983)
+- count spikelet meristems (include those that have developet into floret meristems or florets) on the MSA
