Think about to fix the issues found by adapter checker

[ioBrokerChecker]

I am an automatic service that looks for possible errors in ioBroker and creates an issue for it. The link below leads directly to the test:

https://adapter-check.iobroker.in/?q=https://raw.githubusercontent.com/arteck/ioBroker.bydbatt

• [E144] common.installedFrom field found in io-package.json. Must be removed.
• [E140] width and height of logo are not equal
• [E605] No actual year found in copyright. Please add "Copyright (c) 2018-2022 Arthur Rupp arteck@outlook.com" at the end of README.md
• [E701] No actual year found in LICENSE. Please add "Copyright (c) 2014-2022 Arthur Rupp arteck@outlook.com" at the start of LICENSE

Thanks,
your automatic adapter checker.
