This will default to 4 but will also cap out there. Might want set back to 256.

The expression on line 148 is equivalent to:
!(err == nil || defaultMaxSync)

Fixes #41
Motivation
This commit allows users to specify an env variable MAXSYNC which overrides DefaultConcurrency in rosetta-sdk-go.
Solution
The solution was to add a field to the Configuration struct in the same way as Mode and Network. Then used this value when constructing the syncer to override defaults.
