Double to long int microseconds fails in HLS

[stevemayhew]

The HLS Parser converts from a string decimal duration in seconds into long microseconds. Because the conversion passes through a java double type it can result in representation errors.

For example, durations like:

  #EXTINF:4.004,

or

  #EXTINF:2.002,

will come out to less then 2,002,000 microseconds if converted to double and multiplied by C.MICROS_PER_SECOND

Easy fix is to use the BigDecimal class in Java, which avoids all of this.
