Rendering large amount of events

[Channa53]

Hello,

When trying to load ~ 500 events in one day/week, it takes too long to render (about 5 seconds). If you use innerHTML instead of append function here - https://github.com/Serhioromano/bootstrap-calendar/blob/fd5e6fdb69d7e8afdc655b54ffe7a50b8edfffd1/js/calendar.js#L461

it reduces to 0.1 seconds.

The limitation in innerHTML is that any JS in the template file will not be rendered properly.

Will you agree to apply this change?

Thanks!!
