Do not crash for missing block from Map #417

Open keller-mark opened 8 months ago

keller-mark commented 8 months ago

Hi, I am encountering a case in which readRasters is failing due to encountering an undefined block during readSliceData. An extra check that each block is present in the Map resolves the issue and allows the image channels to load successfully.

The full error stack:

Uncaught (in promise) TypeError: can't access property "offset" of undefined
    readSliceData blockedsource.js:260
    readSliceData blockedsource.js:248
