Fix yanked lz4_flex

[nixpulvis]

error: failed to select a version for the requirement `lz4_flex = "=0.11.2"`
  version 0.11.2 is yanked

[finnbear]

This is a dev-dependency:

bitcode/Cargo.toml

Lines 27 to 32 in d0049d9

	[dev-dependencies]
	arrayvec = { version = "0.7", features = [ "serde" ] }
	bincode = "1.3.3"
	flate2 = "1.0.28"
	glam = { version = "0.22", default-features = false, features = [ "rand" ] }
	lz4_flex = { version = "=0.11.2", default-features = false }

Is there any outside impact of this?

I just noticed when I was building this locally to play with some things. Probably not a huge issue, just thought I'd raise it here.
