Issue about failed curl process

[ASaragga]

Hi

First, would like to thank you very much for this package!

I am having the following issue trying to access some data from the European Central Bank public stats webpage:

nssURL = "http://sdw.ecb.europa.eu/quickviewexport.do?trans=N&updated=&start=&end=&SERIES_KEY=165.YC.B.U2.EUR.4F.G_N_A.SV_C_YM."
symbol = :BETA0
resp = TableReader.readcsv(nssURL*"$(symbol)&format=csvdata", skip = 5, hasheader = false, colnames = [:Date, symbol])

On my macOS Mojave the error message is:

dyld: Library not loaded: @rpath/libssl.1.0.0.dylib
  Referenced from: /Users/ant/.julia/conda/3/lib/libssh2.1.dylib
  Reason: image not found

Thank you! I believe #25 will fix the problem. I'm going to release a new version including that fix very soon.
