No support for HTTP >1 due to Temporal.jl

[ueliwechsler]

Indicators.jl is great, but unfortunately is it inconvenient to use, as the dependency Temporal.jl is not supporting HTTP > 1.

Is Indicators.jl and Temporal.jl still maintained? In case you need help, I am willing to contribute. There is already a PR (https://github.com/dysonance/Temporal.jl/pull/52) but not sure if just bumping up the HTTP version in the .toml file is enough.
