* dirs-sys v0.3.4 -> v0.3.6 to drop a lot of deps
regex v1.3.1 -> v1.4.3 drops thread_local 0.3.6
bytecount v0.6.0 -> v0.6.2 replaces packed_simd with packed_simd_2
ignore v0.4.11 -> v0.4.17 drop crossbeam-channel v0.4.0

* itertools 8.0 -> 9.0
bump `ignore` version in Cargo.toml

* cargo_metadata 0.8 -> 0.12
