use_fast_ramp_up

bool esb_config::use_fast_ramp_up

When this feature is enabled, radio TXEN and RXEN delays are reduced from 130 µs to 40 µs. The radio peripheral needs some time to start up analog components of the radio. On the nRF51 and nRF24L Series devices, a hard-coded 130 µs delay is implemented. If ESB connection is achieved only between nRF52 and/or nRF53 Series devices, this delay can be reduced to 40 µs.
