Decision No. 4004-01DEC-CRA, 8th Edition - February 2019,
Radiocommunications and Regulatory Organization.
General radio license for the use of parts of the frequency bands
2400-2483.5 MHz, 5150-5250 MHz, 5350-5250 MHz, 5470-5725 MHz, and
5850-5725 MHz in radio access networks. [1]

* 2400 - 2483.5
  - 100 mW e.i.r.p
  - 10dBm in every 1Mhz
* 5150 - 5250
  - 200 mW e.i.r.p
  - 10dBm/MHz per 1MHz bandwidth or -6dBm/25kHz per 25kHz bandwidth
* 5250 - 5350
  - 200 mW e.i.r.p
  - 10dBm/MHz per 1MHz bandwidth
  - DFS
* 5470 - 5725
  - 1000 mW e.i.r.p
  - 17dBm/MHz per 1MHz bandwidth
  - DFS
  - If TPC is not used, the maximum radiated e.i.r.p. must be reduced
    by 3dB.
  - Outdoor use only
    (Since NO-INDOOR flag is not supported by current format, don't add
     this entry.)
* 5725 - 5850
  - 4000 mW e.i.r.p
  - 36dBm in every 500 kHz
  - DFS
  - Outdoor use only
    (Since NO-INDOOR flag is not supported by current format, don't add
     this entry.)

Thanks for the suggestion. I have made a patch to allow NO-INDOOR flag, but
not parse into binary.

Since I'm very not familiar with Python, please review the patch carefully.
Thank you.
