v1.15.5

Server

• Add env var SUBSTREAMS_PRINT_STACK to enable printing full stack traces when caught panic occurs
• Prevent a deterministic failure on a module definition (mode, valueType, updatePolicy) from persisting when the issue is fixed in the substreams.yaml #621
• Metering events on tier2 now bundled at the end of the job (prevents sending metering events for failing jobs)
• Added metering for: "processed_blocks" (block * number of stages where execution happened) and "egress_bytes"

CLI

• Add unichain to the list of supported chains.
