shouldn't crash when there's an exception during parsing

[vincent-fuchs]

Summary

#38 was raising a concern of a parser not able to parse yml file in some conditions. While the problem was with the file, it's not normal that the crawler crashes and stops : exception should be handled, and processing should continue

Type of Issue

It is a :

• bug
• request
• question regarding the documentation

Motivation

We want the crawler to complete its job on all repos, even if there were some parsing issues at some point

Current Behavior

crawler crashes if there's a parsing exception, at least for yaml parser (see issue #38 )

Expected Behavior

it should report the indicator value as "parsing error", and continue with the rest of the processing
