Multi-SIM card support

[vestrel00]

Problem

The current Sim CRUD APIs provided in this library does not explicitly support multi-SIM card configurations…

Solution

Buy a device with two or more SIM card slots, two or more SIM cards, and update the SIM APIs accordingly.

To get started, use the findings shared by @lt692 in #335 (comment)

for multiple SIM we need to use this URI:
content://icc/adn/subId/<number>
e.g.:
content://icc/adn/subId/1 will use the first SIM, > content://icc/adn/subId/2 will use the second SIM.
