Add LERC compression to libtiff

[evetion]

@Crghilardi added LERC to Yggdrasil 👍🏻. Ping to @visr because of #4537 which can be closed if this works.

From my quick checks this seems to work:
[13:50:38] LERC support: yes

Exception is the latest macs, there we have
##[warning]Dependency LERC_jll does not have a mapping for artifact LERC for platform aarch64-apple-darwin20-libgfortran5-cxx11 which probably needs to be solved in LERC_jll itself. edit: I've made #4539 for that.

Yeah, you may want to rebuild LERC_jll before this one

@giordano Could you restart the CI here? I'd expect it will pick up LERC v3.0.0+1 automatically now, we don't want to pin that here.

[giordano]

Not before JuliaRegistries/General#55890 is merged. Also, we can't just restart CI, you have to make a dummy edit to the file to actually retrigger the build, if nothing changes we reuse the cache from the previous build.

edit: I've been ninja-ed by @giordano again. 👍🏻
