TUmine updated - fixed background service problems

This update fixes issues with the background service and the job scheduler service, also adds the ability to use background service instead of a job on newer androids (even tho not recommended)

You can download .aar library below (importing using gradle is recommended).

Fixed a bug when starting the miner

Added some more null safety, fixed a bug which can potentially start the miner twice.
The mining binary is force closed after 400ms delay if can't close itself.

The whole Library rewritten

With this update I rewrote big parts of the c++ code, rewrote the Kotlin library to Java, fixed some bugs.
Big changes:

• new algorithms available (compatible with march monero hard fork): See all algorithms
• big hashrate improvements for arm64 and x86 devices, OnePlus 5T on Pie can mine with 60 to 70 H/s on 4 cores (the cpu in it has 8 cores)
• added a buying option on my website for a version of the miner which can't be killed by the system (no root required).
