move copy function to tilelive.js and export
super messy
debug
switch out uris for actual src/dst
pass in progress function and add withoutprogress option
add job option
move loadsrc and dst to tilelive.copy function
handle list stream option
pass in uri string and register modules from caller
remove repeat
list still causing trouble
lists fixed
log error for unlink
print error from filepath unlink
move concurrency and fix event handlers
make withoutprogress less confusing, simple flag
add s3 and register for testing s3 copies
only used for verifying s3 put, but this should live in the caller's tests
actually call callbacks
add and update tests for tilelive.copy()
