May be bugs and disagreements between java and javascript implementation

[alxndrsn]

• Test data starts at 2000 BS: https://github.com/medic/bikram-sambat/blob/master/test-data/daysInMonth.json
• javascript implementation starts at 2007 BS: https://github.com/medic/bikram-sambat/blob/master/js/src/index.js#L7
• 3rd party implementation suggests that our days-in-month for year 2000 BS are incorrect: https://github.com/medic/bikram-sambat/blob/master/test-data/daysInMonth.json#L2 vs https://github.com/bahadurbaniya/Date-Converter-Bikram-Sambat-to-English-Date/blob/master/src/main/java/np/com/converter/date/nepali/Lookup.java#L233, even though this implementation seems to agree with ours for dates output

Steps forward:

1. write new level of testing which tests the output of our javascript and java implementations against each other
2. write new level of testing which tests the output of our java or javascript against implementation at https://github.com/bahadurbaniya/Date-Converter-Bikram-Sambat-to-English-Date
