Error when trying to change a Channel parameter of type Bool

[TheoBr24]

On Windows 10, Julia 1.6.3, using SoapySDR Hardware: Adalm-Pluto SDR

When I try to configure a parameter of a SoapySDR.Channel of type "Bool", I get this error:

"setfield! immutable struct of type Channel cannot be changed Stacktrace: [1] setproperty!(c::SoapySDR.Channel, s::Symbol, v::Bool) @ SoapySDR C:\Users\Theo.julia\packages\SoapySDR\saW3b\src\highlevel.jl:338 [2] top-level scope @ REPL[5]:1"

Is this a bug or do I have to transform the boolean somehow with Unitful.jl?

This is a bug that should be fixed on the main branch. I will clean up the docs tonight and get a 0.1.1 release out ASAP.
