Read flash function (ESF-93)

[rnadyrshin]

Is your feature request related to a problem?

The esp-serial-flasher library flashes very well.
But sometimes i need to read a flash in the field with a small device, without a computer. Reading support would be very helpful

Describe the solution you'd like

Read function in esp-serial-flasher or other c/c++ library

Describe alternatives you've considered

Hello @rnadyrshin , this is a stub-only feature. We will look into adding support for the flasher stub and implementing those features, this issue will be kept as a feature request in the meantime.

It turns out that there is indeed a command that can be used to read memory in the ROM, we will explore adding this feature.
