Granules with very large feature counts cannot be added to hydrocron due to lambda timeout

[torimcd]

Some granules contain upwards of 140,000 feature records (eg SWOT_L2_HR_LakeSP_Prior_020_123_AR_20240825T010843_20240825T011234_PIC0_01.zip). The lambda that submits the records to be inserted into dynamodb times out after 10 minutes during unpacking the features from the shapefile and adding units and other info from the filename to each record.
My guess is this is mostly due to the for loop here:

hydrocron/hydrocron/db/io/swot_shp.py

Line 182 in 7396ac1

def assemble_attributes(geodf, attributes):

Because this happens during the granule unpacking none of the features get loaded before the timeout.
