handle the argument input like NaN.bs2ad('2075/04/00')

[ohmmee]

.bs2ad('2075/04/00') gives out the last month's converted date
if possible, handle the way the input is received

like if('2018/02/31') is passed as an argument for ad2bs then, it also gives out result
which is absurd because feb cant have 31 days

Good point. Always good to add additional validations around the input. While I think it would be great to have this, I don't have bandwidth myself to work on this. If I find time, I may try to crack this problem and get it figured. Meanwhile, library/package users should handle that in the current version
