Subject: [PATCH] Update berate_ap

fix for "ERROR: Your adapter can not transmit to channel 1, frequency band 2.4GHz." - see https://github.com/sensepost/berate_ap/issues/12

iw list now seems to add ".0" to the frequency, which causes parsing to fail. may be similar for 5ghz, not tested due to lack of hardware.

```
10:44 root@kali /alex $ iw list | egrep " MHz "
			* 2412.0 MHz [1] (20.0 dBm)
			* 2417.0 MHz [2] (20.0 dBm)
			* 2422.0 MHz [3] (20.0 dBm)
			* 2427.0 MHz [4] (20.0 dBm)
			* 2432.0 MHz [5] (20.0 dBm)
			* 2437.0 MHz [6] (20.0 dBm)
			* 2442.0 MHz [7] (20.0 dBm)
			* 2447.0 MHz [8] (20.0 dBm)
			* 2452.0 MHz [9] (20.0 dBm)
			* 2457.0 MHz [10] (20.0 dBm)
			* 2462.0 MHz [11] (20.0 dBm)
			* 2467.0 MHz [12] (20.0 dBm)
			* 2472.0 MHz [13] (20.0 dBm)
			* 2484.0 MHz [14] (disabled)
