Link TCGA H&E imaging resources at slide level and add pathology metadata from GDC

[rmadupuri]

Regenerated data_resource_patient.txt for all 32 TCGA Pan-Cancer Atlas 2018 studies.

Two changes:

1. Slide microscopy is now linked per series instead of per study. IDC shows all H&E images in the SLIM viewer and hence one representative image was picked earlier. Since metadata is availble for each slide, all H&E seriesUIDs are pulled.
2. A new METADATA column with tumor/necrosis/stromal percentages, immune infiltration, section location etc., is added

Radiology linking is unchanged: still one row per patient/study/modality, since OHIF loads the whole study.
