Unicorn rust bindings `ctl_set_cpu_model` function

[bonnefoi]

Is it possible to set the CPU variant as UC_CPU_ARM_CORTEX_M4 provided in [unicorn/bindings/rust/src/arm.rs at dev · unicorn-engine/unicorn](https://github.com/unicorn-engine/unicorn/blob/dev/bindings/rust/src/arm.rs) ?
I need it to get access to thumb instruction set.
