Run IQ-TREE natively in ARM64 image

[victorlin]

Context

Currently, IQ-TREE version 2.1.2 is used in the Docker image with a note that it requires emulation on non-amd64 hosts:

docker-base/Dockerfile

Lines 125 to 132 in 822a459

	# Download IQ-TREE
	# NOTE: Running this program requires support for emulation on the Docker host
	# if the processor architecture is not amd64.
	# TODO: Build from source to avoid emulation. Instructions: http://www.iqtree.org/doc/Compilation-Guide
	WORKDIR /download/IQ-TREE
	RUN curl -fsSL https://github.com/iqtree/iqtree2/releases/download/v2.1.2/iqtree-2.1.2-Linux.tar.gz \
	| tar xzvpf - --no-same-owner --strip-components=1 \
	&& mv bin/iqtree2 /final/bin/iqtree

Possible solutions

1. Build IQ-TREE by ourselves. This will increase build times. I tried a bit here: 0ff5492...120bbcf
2. Use IQ-TREE version 2.3.4 which provides prebuilt binaries for both amd64 (intel) and arm64 (arm). Do this by conditionally determining the binary based on TARGETARCH similar to how csvtk is downloaded.

Another solution, use the bioconda binaries, which have linux-aarch64 builds available:
