Reduce memory consumed when parsing Entity List CSV

[lognaturel]

ODK Collect version

v2024.2.1, #6318

Android version

Android 14

Device used

Galaxy A13

Problem description

Parsing a large Entity List is currently done with JR functionality which always reads the whole instance into an in-memory XML representation. This can lead to OOM exceptions on devices like this A13.

Steps to reproduce the problem

Download a form with a large attached entity list. See an OOM.

Expected behavior

The form is parsed without using up significant memory.

Other information

Values from CSV should go directly into the database without going through the in-memory representation.
