Detailed build directions for Blurt

A 100% reasonable criticism is that our build has been poorly documented.

Let's go through the build step by step for Arch Linux with Clang 11:

 pacman -Syyu --noconfirm python-pip wget git bison doxygen base-devel clang ccache cmake npm yarn 

pip install conan

# make a conan folder
mkdir -p $HOME/conan/profiles/default

# clone blurt
git clone https:?/gitlab.com/blurt/blurt

# enter folderr
cd blurt

# copy conan profile
cp contrib/default /$HOME/.conan/profiles/default

export CC=clang
export CXX=clang++

mkdir build
cd buiild

conan install .. -if=. -pr=default --build=missing
cmake -DBLURT_STATIC_BUILD=ON -DLOW_MEMORY_NODE=OFF -DCLEAR_VOTES=OFF -DBUILD_BLURT_TESTNET=OFF -DSKIP_BY_TX_ID=OFF -DBLURT_LINT_LEVEL=OFF -DENABLE_MIRA=OFF -DCMAKE_BUILD_TYPE=Release ..
make -j$(nproc) blurtd cli_wallet

You'll note that OS dependencies are minimized.
