How to use RTL-SDR v4 with Windows

[xoolive]

The current installation instructions for Windows involve installing PothosSDR

• https://github.com/xoolive/rs1090/blob/master/.github/release_setup.yml
• https://mode-s.org/jet1090/install/#powershell-windows

But the latest release of PothosSDR is quite late (2021.07.25) and doesn't cover RTL-SDR v4.

The following workaround does the job though:

• download RTL-SDR latest release (currently 1.3.6)
  https://github.com/rtlsdrblog/rtl-sdr-blog/releases
• unzip the folder and copy the content of x64/ into C:\Program Files\PothosSDR\bin

Note that this is valid with soapy extra. Maybe we should take this into account for an implementation based on rtl-sdr-rs (see #264 #294) although current release does not cover v4 either. We could consider contributing there for that aspect as well.

Also, confirm instructions with Linux and MacOS

Quick note: ccostes/rtl-sdr-rs#24 added support for V4 in rtl-sdr-rs==0.2.0 and I can confirm it works well
