Nvdlib

-------------------
**Bugfixes**

- Fixed the location of `baseSeverity`. The `baseSeverity` attribute had its location changed and caused lookups with a CVSS version 2 score to fail.

-------------------

- Overhauled NVDLib to utilize the new version of the NVD API (version 2).
- `nvdlib.getCVE()` no longer exists and is now combined into `nvdlib.searchCVE()` using the `cvdId` parameter.
- `nvdlib.searchCPE()` no longer has the `cves` parameter to pass CVEs.
- New parameters for `nvdlib.searchCVE()`

Happy Halloween! 🎃

-------------------
**Bugfixes**

- Updated `cve.py` to utilize the correct parameter to allow sorting by exact match. The parameter is `isExactMatch` with a value of `True`. The argument used in `searchCVE` is still `exactMatch` with a value of `True`, NVDLib will now use the correct parameter when building the search query.

-------------------
**Bugfixes**

- Updated `cve.py` to utilize the correct parameter to allow sorting of CVE collections by date. The parameter is `sortBy` with a value of `publishDate`. By Smjert in https://github.com/vehemont/nvdlib/pull/8

-------------------
**Bugfixes**

- Update `get.py` and `cve.py` to set the request encoding to `utf-8` to prevent any incorrect decoding of requests.

**Improvements**

- Update `cve.py` to add a request timeout of 30 seconds.
- Updated `get.py` to enhance the `verbose=True` parameter to work with `searchCVE` and `searchCPE` and it will now print the parameters with each query to see what page a request is failing on, as utilizing `.raise_for_status()` to raise an HTTPError object if an error occurs during the request (such as 403 forbidden from too many requests).

-------------------
**Bugfixes**

- Update get.py and cve.py by GamehunterKaan in https://github.com/vehemont/nvdlib/pull/5
- Removed exit() function that causes the program to abort. Modules shouldn't exit.
- Updated cve.py `searchCVE` doc string to include the `cweId` parameter.

**Improvements**

- Updated cve.py to include the `sortPublished` parameter that is supposed to sort a CVE collection by published date, rather than the default modified date. In my testing, I have not been able to get this parameter working as expected, and I receive no changes in response with or without the `sortOrder=publishedDate` parameter.
I have decided to include the parameter since it is a valid API parameter. The NVD developer guide (https://nvd.nist.gov/developers/vulnerabilities) recommends to use this parameter to prevent missing CVEs when searching for large amounts of CVEs.
