Cleanup more trait bounds

[insipx]

We can clean up trait bounds on our structs that we could not before due to Restioson/xtra#42

[dvdplm]

Is this still relevant? What structs do you have in mind here?

[insipx]

Yeah! Still relevant. The PR I Linked allows us to remove the Send + Sync bounds from our Actor-struct declarations, like here for example:

substrate-archive/substrate-archive/src/actors/workers/blocks.rs

Line 42 in ff02024

pub struct BlocksIndexer<B: Send + 'static, D: Send + 'static> {

which will have a ripple effect and hopefully clean up the code elsewhere as well

[dvdplm]

I see, ok. But the PR is not released yet, so we can't do this yet right?

[insipx]

yeah we're just waiting on a release of xtra. Not really high on priorities since it won't change the functionality of archive in any way other than improve the code quality
