ModuleNotFoundError: No module named 'base58

### Step 1: Please describe your environment

* ZeroNet version: 0.7.2-1
* Operating system: archlinux (kernel 5.15.7-arch1-1)
* Web browser: Brave Version 1.33.106 Chromium: 96.0.4664.110 (Official Build) (64-bit)
* Tor status: not available
* Opened port: no
* Special configuration: ____

### Step 2: Describe the problem:

#### Steps to reproduce:

1. systemctl start zeronet
2. systemctl status zeronet

#### Observed Results:

`systemctl status zeronet` is returning this:

```
Dec 14 20:12:35 user zeronet[56115]: from .ecc import ecc
Dec 14 20:12:35 user zeronet[56115]: File "/opt/zeronet/src/lib/sslcrypto/openssl/ecc.py", line 4, in
Dec 14 20:12:35 user zeronet[56115]: from .._ecc import ECC
Dec 14 20:12:35 user zeronet[56115]: File "/opt/zeronet/src/lib/sslcrypto/_ecc.py", line 4, in
Dec 14 20:12:35 user zeronet[56115]: import base58
Dec 14 20:12:35 user zeronet[56115]: ModuleNotFoundError: No module named 'base58'
Dec 14 20:12:35 user zeronet[56115]: - Starting ZeroNet...
```

on the browser zeronet websites are returning `This site can’t be reached`

#### Expected Results:

all zeronet websites should be accessible after `systemctl start zeronet` command

Reproduce the failure with `systemctl start zeronet` and inspect the traceback through `src/lib/sslcrypto/_ecc.py`, where the missing `base58` import is reported. Check how the service's Python dependencies are installed; done means the service starts successfully and ZeroNet websites are accessible.
