Well names are badly named for 1536-well plates

[dlogan]

1536-well plates have 32 rows, and so it complicates the alphabetical row-naming-scheme. Typically, vendors use the well naming convention of A-Z and then AA, AB, ... AF. My 1536-well output from pe2loaddata is A01,...,Z48, but then ...,[01,...,\01,...,]01,...,^01,...,_01,...,`01,... These are the Unicode characters after the upper-case letters.

Looks like this is the culprit:

pe2loaddata/src/pe2loaddata/content/item/item_handler.py

Line 43 in bb98428

return chr(ord('A') + row - 1) + ("%02d" % col)

pe2loaddata doesn't error, but it seems to me that this needs to be generalized to plates >384 wells.
