Problem with ADC next to RF object

[cncastillo]

Sometimes when an ADC is beside an RF object the RF object is not simulated. Minimal working example:

seq = Sequence()
seq += RF(B1,T)
seq += ADC(N, T)
seq += RF(B1,T)

The problem does not appear when N=1 as the function get_adc_sampling_times interprets that cases differently. A solution would be to sample the ADC from $0 + \epsilon$ to $T -\epsilon$, with $\epsilon$ a very small number, so it can never happen that the start/end of an RF coincides with an ADC sampling point.
