Resolve security advisory

[martinfrances107]

I love this project .. I am trying to get a long chain of security advisory warnings resolved from a project I am working on

When I run cargo audit on this project I get this warning

Crate:     time
Version:   0.1.45
Title:     Potential segfault in the time crate
Date:      2020-11-18
ID:        RUSTSEC-2020-0071
URL:       https://rustsec.org/advisories/RUSTSEC-2020-0071
Severity:  6.2 (medium)
Solution:  Upgrade to >=0.2.23
Dependency tree:
time 0.1.45
└── chrono 0.4.26
    └── theta-chart 0.0.5
        └── leptos_chart 0.1.0

I have created these issues in theta-chart and chrono

When those are complete the fix here will be simple.

Thanks you,

• Temporarily update to version 0.1.2 while waiting for chrono to fix.
