Bump dependency on Boost to >= 1.68

We used to depend on >= 1.54, but in a809629 we accidentally raised the minimum required Boost version to 1.68 (boost::optional::has_value() was introduced in that version to align with std::optional). This version of Boost is 5 years old though, so instead of modifying our code to cope with older versions, we're probably better off declaring a higher minimum version. This was the original cause of #13, and thus it should prevent this issue from happening again in the near future. Signed-off-by: Rodrigo Tobar <[email protected]>
