As reported by @dragosmg the following:

StrptimeOptions options("%m/%d/%Y", TimeUnit::MICRO, /*error_is_null=*/true);
std::string input2 = R"(["5-1-2020", "12/13/1900"])";
std::string output2 = R"([null, "1900-12-13"])";
Strptime(input2, options)

Would cause:

Expected:
[
null,
1900-12-13 00:00:00.000000
]
Actual:
[
null,
1970-01-01 00:00:00.000000
]

This was due to out_data pointer not updating on failed parsing.

This change fixes the issue and adds a test.
