Missing `cd build` command in Quickstart

[dagardner-nv]

In the Quickstart code block at https://python-hyperscan.readthedocs.io/en/latest/#quickstart

I believe that this:

$ git clone https://github.com/intel/hyperscan.git
$ mkdir -p hyperscan/build
$ cd hyperscan
$ # PCRE1 (8.xx series) is required for Chimera support
$ wget -qO- https://sourceforge.net/projects/pcre/files/pcre/8.45/pcre-8.45.tar.gz/download | tar xvz
$ git checkout v5.4.0
$ cmake -DCMAKE_INSTALL_PREFIX:PATH=/usr \
    -DBUILD_STATIC_AND_SHARED=ON \
    -DFAT_RUNTIME=ON \
    -DPCRE_SOURCE=../pcre-8.45 \
    ../
$ # Compile with all available cores:
$ # make -j $(( $(nproc) + 1 ))
$ make
$ sudo make install

Should be changed to:

$ git clone https://github.com/intel/hyperscan.git
$ mkdir -p hyperscan/build
$ cd hyperscan
$ # PCRE1 (8.xx series) is required for Chimera support
$ wget -qO- https://sourceforge.net/projects/pcre/files/pcre/8.45/pcre-8.45.tar.gz/download | tar xvz
$ git checkout v5.4.0
$ cd build
$ cmake -DCMAKE_INSTALL_PREFIX:PATH=/usr \
    -DBUILD_STATIC_AND_SHARED=ON \
    -DFAT_RUNTIME=ON \
    -DPCRE_SOURCE=../pcre-8.45 \
    ../
$ # Compile with all available cores:
$ # make -j $(( $(nproc) + 1 ))
$ make
$ sudo make install

Another issue I noticed was in the Match Event Handling section code block:

def on_match(
    id: int,
    from: int,
    to: int,
    flags: int,
    context: Optional[Any] = None
) -> Optional[bool]:
    ...

from is a reserved word and cannot be used as an identifier and will raise a SyntaxError: https://docs.python.org/3.10/reference/lexical_analysis.html?highlight=reserved#keywords
