v2.0.8

Core Changes:

• Substract 5 blocks from latest reported block to avoid reorgs while executing queries. Now block not found errors should be mitigated

API Changes:

• Add 15 days limit for single query in auctions/cleared endpoint. Now cleared auctions should be checked using time periods of maximum 15 days for each query.
• Change custom-price endpoint time parameter to use ISO8601 date instead of Unix timestamp
• Add 404 error when token address is not found.
• Fix date util when checking invalid date format to avoid printing deprecation warning
