Range request not working

Bug report

Describe the bug

Hello, while trying to perform a Range request an exception is thrown as described in the StackTrace below

StackTrace" at 
System.Net.Http.Headers.HttpHeaderParser.ParseValue(String value, Object storeValue, Int32& index)\r\n   at
System.Net.Http.Headers.HttpHeaders.ParseAndAddValue(HeaderDescriptor descriptor, HeaderStoreItemInfo info, String value)\r\n   at System.Net.Http.Headers.HttpHeaders.Add(String name, String value)\r\n   at 
Postgrest.Helpers.<MakeRequest>d__5.MoveNext() 

After debugging I found that issue is when performing a Range request with from parameter only or both from and to the headers expected by Postgrest are :

• Range-Unit : items
• Content-Range : 1-3 (we suppose 1 is the from parameter and 3 is to)

The second header will throw the exception when trying to add it to the HttpRequestMessage.Headers because is not a valid one Exception line

To Reproduce

1. Perform a Range request

   var response = await client.Builder<User>().Range(2).Get();

Expected behavior

• Get a response with the requested size
