Make ability to set DebugSequence externally

[Kuraga13]

    /// Set DebugSequence on Target. Change sequence external, on runtime etc.
    pub fn set_debug_sequense(&mut self,  sequence : DebugSequence) {
        self.debug_sequence = sequence;
    }

motivation

there is no need to add config to the project i.e. each sequence, this can be done externally, including at runtime

example

/* add externally target from YAML */
const SOME_ARM: &[u8] = include_bytes!("../arm_target/arm_targets_yaml/SOME_ARM.yaml");
...
probe_rs::config::add_target_from_yaml(SOME_ARM).map_err(|err | Error::InternalError("add_target_from_yaml SOME_ARM".to_string()))?;
...
/* init target sequence */
let debug_sequence = if target.name.starts_with("SomeArm") {
 DebugSequence::Arm(SomeArm::create())
} else  { DebugSequence::Arm(DefaultArmSequence::create()) };
 target.set_debug_sequense(debug_sequence);

Sorry, It's not ideal that everything is combined in one PR. FlashAlgorithm assemble_from_raw_with_data also to be updated in this pull request. Allow page_size = 2, as used in the EEPROM flash algorithm, for example, mke02zxxx_ee256b. Also, for the USB interface on StLink, use the interface_number from the descriptor.
