When to use in-place outputs in IndicatorFactory?

[andreas-vester]

I don't fully understand the difference between regular outputs when using IndicatorFactory and its in-place counterparts as described in the docs (https://vectorbt.dev/api/indicators/factory/#outputs).

When would it be clever to use in-place outputs? What are typical use-cases?

@andreas-vester it's mostly a matter of preference. In-place outputs are usually used if you have an array of data that should be modified in place, or when returning an array isn't possible (like in SignalFactory where signals are placed in-place). Both types behave the same way otherwise.
