Handle S3 objects whose names include characters that are invalid for Synapse

[BrunoGrandePhD]

Currently, the Lambda function fails when trying to synchronize a new object to Synapse when the file name contains invalid characters (e.g. &). Specifically, these characters are allowed by S3 but not allowed by Synapse. Hence, the file will exist in S3 but not in the corresponding Synapse project.

Here's the error that I found in the Lambda function logs:

synapseclient.core.exceptions.SynapseHTTPError: 400 Client Error: 
Invalid Name: '0000350121_H&E_A1.ome.tiff'. Names may only contain: letters, numbers, spaces, underscores, hyphens, periods, plus signs, apostrophes, and parentheses
