Cannot add entries of value type int, but only float

[XikunZhang]

pybigwig version: 0.3.18

When I tried adding entries of int type like

import pyBigWig
import numpy as np
hg19_chr1_len = 249250621
with pyBigWig.open("/path/to/a/bigwig", "w") as bw:
    bw.addHeader([("chr1", hg19_chr1_len)])
    bw.addEntries("chr1", [0], values=[0], span=hg19_chr1_len)

, I encountered this error

RuntimeError: You must provide a valid set of entries. These can be comprised of any of the following:
1. A list of each of chromosomes, start positions, end positions and values.
2. A list of each of start positions and values. Also, a chromosome and span must be specified.
3. A list values, in which case a single chromosome, start position, span and step must be specified.

. After I changed the value type from int to float, like

import pyBigWig
import numpy as np
hg19_chr1_len = 249250621
with pyBigWig.open("/path/to/a/bigwig", "w") as bw:
    bw.addHeader([("chr1", hg19_chr1_len)])
    bw.addEntries("chr1", [0], values=[0.], span=hg19_chr1_len)

, the code ran successfully. I think it can be good to allow adding entries of int type.

BigWig files themselves only support float values.

OK, but it can be good to auto-convert integers to floats or give more interpretable error messages. The current error message is not helpful to let people know what is going wrong.
