When using USB-serial-jtag for monitoring idf-monitor will lose connection
during deep sleep (because the peripheral powers down) and will need
some time to reconnect when we wake-up. In the ULP examples this would result in
the chip waking up->printing-> going back to sleep, before idf-monitor is even able
to connect, and users would erroneously assume the chip never woke up.
Add a 1 sec delay at the start of the examples to improve the user experience when
using jtag-serial.
This commit adds a driver for reading the touch sensor from the ULP
RISC-V core during sleep. The commit also adds an example to demonstrate
this feature.
