v3.1.0

Features:

• Full support for both listObjects API versions (#424)
  • Specifically, for v2 this adds start-after, continuation-token, and fetch-owner support, and for both versions all the expected elements (MaxKeys, KeyCount, NextMarker/NextContinuationToken) in responses

Fixes:

• Using marker in listObjects wouldn't work
• Handle an edge case where calling listObjects with maxKeys = 0 should report no truncation
• Date header ignored when validating signed AWS requests (#448)
• copyObject incorrectly writes over object contents when generating MD5 (#455)

Tooling:

• Update fs-extra to v8 (#454)
• Update dependencies (#444 #445 #446 #450 #451 #452 #453 #456 #457)
