Kotlin Multiplatform BigInteger library.

Platform	Implementation
JVM	BigInteger
Android	BigInteger
JS	BigInt*
Native	LibTomMath
WASM	Not implemented

^* Kotlin/JS does not fully support BigInt (KT-48980).

Kotlin does not support BigInteger and BigDecimal types in multiplatform projects (KT-20912).
However, I was not interested in BigDecimal so this library only implements BigInteger.
Serialization is implemented in a separate module so the main library can be used on its own.

• Fully custom implementation.

• No serialization.
• Custom Native implementation.

• No serialization.
• Fully custom implementation.

• Internal library.
• No serialization.
• Depends on Apache Commons Math in JVM.
• Only Linux is supported in Native (using gmp).

• No longer updated.

• Stub JS implementation.
• No Native implementation.
