sbws does not detect changes in descriptor bandwidth values

See attached files. Relay powerlay lowered max advertised bandwidth late 5/23. SBWS longclaw never recognized the change. SBWS bastet saw the value but was started after the change. Torflow recognized the change instantly.

~~ Have observed that SBWS, when it makes note of max advertised bandwidth, averages the value. This value should not be averaged, the current value whatever it is apples. ~~
