…efault 2); test Zephyr default USB SMP server example; refactor examples folder layout

This fixes some problems with USB/serial DFU defaults and compatibility. Adds some examples of USB DFU to the main app. Would like to add an example of a faster upload and an example of an MCUBoot single slot upload.

Fixes #22 Fixes #19 (allow user to not send SHA)

@tomaszduda23 I think this might be right. LMK what you think. The serial transport takes optional args for line length, line_bufs, and total size. They get used in a few places to slice the upload chunks.

This is an NRF52840DK example: python -m examples.usb.upgrade nrf52840dk_nrf52840

I've determined that these are the three settings that matter and correspond to line length, line buffers, and "max encoded size", respectively. Examples are in the dutfirmware folder.

CONFIG_UART_MCUMGR_RX_BUF_SIZE=1024
CONFIG_UART_MCUMGR_RX_BUF_COUNT=1
CONFIG_MCUMGR_TRANSPORT_NETBUF_SIZE=1024
