very small numbers get written into URLs with error-raising scientific notation

[itcarroll]

A very small number, for instance a coordinate very close to the equator, can get written to string as scientific notation when cmr.queries.Query._build_url() is called. For example:

from cmr import GranuleQuery

q = GranuleQuery().short_name("FOO").point(42, 0.00001)
q._build_url()

'https://cmr.earthdata.nasa.gov/search/granules.json?short_name=FOO&point[]=42.0,1e-05'

To this request, CMR responds:

{"errors":["[42.0,1e-05] is not a valid URL encoded point"]}
