Re total runtime of WalletDB.write() and file size on disk,
for a large encrypted wallet, compare:

before (zlib level=6):
file size 16_670 KB
JsonDB.dump 0.5099 sec
zlib.compress 1.3280 sec
ECPubkey.encrypt_message 0.1720 sec

after change (zlib level=1):
file size 17_527 KB
JsonDB.dump 0.5344 sec
zlib.compress 0.5320 sec
ECPubkey.encrypt_message 0.1837 sec
