Analyzer merge should not take previously created result file into account.

if you run the anlyzer twice the previous result file codeprints_merged.json is merged again. The total count is increased with every execution.

Output file: codeprints_merged.json

Expected: the process is deterministic and the result file is ignored.

We could call the output file merged_codeprints.json or something so that the glob doesn't match.

analyzer/src/bin/analyzer/main.rs

Line 62 in 86202e4

for entry in glob("codeprints*.json")? {

This should be fixed now in #4.
