[bug] An unneeded space is outputted when there is a rule parsing error

[YamatoSecurity]

Describe the bug
When there is a rule parsing error, hayabusa will print blank lines.

Step to Reproduce
パースエラーを起こすルール（例: 変換されていない元々のSigmaルール）を使うと、例えば980件のパースエラーがあった場合、980行の改行が入ってしまいます。
./hayabusa-1.8.1 -d ../hayabusa-sample-evtx -o hogehoge.csv -r ../sigma/rules/windows

Expected behavior
Hayabusa shouldn't print unneeded lines so it is easy to read what is above.

Screenshots

Environment (please complete the following information):

• OS: mac
• hayabusa version: I think this happens up until 1.8.1
